Post Internal Research Fellow Postdoc in OnBoard Data Processing This post is classified F2 on the Coordinated Organisations salary scale. Location ESTEC, Noordwijk, The Netherlands Description Onboard payload data processing work is based in the OnBoard Payload Data Processing Section in the Data Systems and Microelectronics Division at ESTEC. Our competences include Data processor architectures Data acquisition chains High speed onboard networks Digital signal processing, processors and specialised devices Payload data storage Image and signal processing algorithms Data compression techniques High rate data encryption As part of ESAs Directorate of Technical and Quality Management, the Section provides technical support in its domain of competence to all programme directorates in order to support their missions and developments. The Section is also responsible for initiation and execution of technology developments that may lay the foundation for future missions. This comprises developments in analogue and digital hardware from components to subsystems and building blocks, lowlevel software and novel signal processing techniques. In particular, the Section hosts the centre of expertise for data compression algorithms, techniques and devices. It has initiated the development and standardisation of SpaceWire and SpaceFibre links, nodes and networks which have become very widely used not only in nearly all European space missions but also in the US, Japan, Russia and around the world. Interested candidates are encouraged to visit the ESA website for more information regarding the Divisions activities. Fields of activitiesresearch This research fellow position provides an opportunity for interested researchers to enhance the understanding of how reconfigurable spacequalified and COTS FPGAs, such as Microsemi RTG4 flashbased, Xilinx Virtex Zynq and ESAs BRAVE SRAMbased, can be implemented in current and future on board data processing units in an efficient way. While the fault tolerance of such devices is a rich research topic on its own, the research will be focused on how these devices are best used from a system engineering perspective, including The upload of full bitstreams to the spacecraft and the partial patching of bitstreams, including an investigation of possible compression schemes for interplanetary missions with lowspeed upload data rates The storage of bitstreams in memory, including an analysis of the optimal location and the required mechanisms e.g. to load the bitstream from a mass memory unit to the working memory of the payload instrument, to verify the correctness of the transfer and to execute scrubbing of the memory, if required The full and depending on the device technology partial configuration of the FPGA depending on mission phases or processing tasks to be performed. This crucial step requires special attention to ensure that neither the device itself nor any attached device is harmed due to a faulty configuration. An analysis should show up potential risks e.g. accidentally reprogrammed InputOutput blocks and suggest fault isolation schemes on unit level Even if it is known that the bitstream is downloaded correctly to the FPGA device, it would be interesting to execute some basic hardware validation before operation. For instance, the implemented hardware could be tested in flight, by stimulating it with test vectors on its inputs and by comparing its outputs to a known signature. It could be researched how to store and compress the vectors efficiently and how to write and read them tofrom the device JTAG boundary scan, NAND tree etc. A boot loader concept that implements similar to a software boot loader TMTC functionality to execute the abovementioned steps upload, download, decompression, memory copy, memory verification, full and partial reconfiguration of the FPGA, verification of correct functionality of the FPGA. The boot loader should also take into account i systems with multiple FPGAs, and ii systems that use the FPGAs as accelerators i.e. that want to dynamically request the installation of new hardware blocks from a main software running on a microprocessor. A tradeoff study could reveal the pros and cons of implementing this boot loader i external to the instrument, e.g. within the onboard computer, ii within the instrument in a dedicated microprocessor and iii even within the FPGA itself in either a hard or soft microprocessor.

Research Fellow opportunity in the Directorate of Technology, Engineering and Quality. ESA is an equal opportunity employer, committed to achieving diversity within the workforce and creating an inclusive working environment. Applications from women are encouraged. Post Internal Research Fellow PostDoc in AOCS and Pointing Systems This post is classified F2 on the Coordinated Organisations salary scale.

The section objectives more particularly related to the proposed Research Fellowship activities are highlighted in bold in the above list. Interested candidates are highly encouraged to visit the ESA website www.esa.int Fields of activitiesresearch Experimental validation of advanced active microvibration mitigation strategies. Attaining high pointing stability performance is a critical objective for many current and future space missions. As lineofsight stability requirements get tighter, mechanical vibrations become one of the key performance limiting factors. Commonly termed microvibrations, these lowamplitude disturbances span a wide frequency range from few Hz up to 1 kHz and are produced by a variety of mechanical and electrical spacecraft systems. Microvibrations can propagate, through the structure of the spacecraft, towards the various optical or communication systems severely degrading their performance. It is critical for mission success to design adequate vibration isolation systems that can minimize their impact. Pure passive isolators, such as the ones based on elastomeric materials, are the current baseline for microvibration mitigation to dampen highfrequency perturbations. Yet, passive isolation methods are limited in the lower part of the microvibration range and can be insufficient in terms of isolation performance. In order to overcome the frequency limitations of a purely passive approach and achieve broadband vibration isolation, the proposed research will focus on the design of a complementary active control strategy that primarly targets the lower range of the frequency perturbations such as the ones introduced by reaction wheels. In order to precisely tune these control strategies and guarantee both compliance with the mission pointing stability requirements and also safeguard against potential uncertainties or faults, accurate dynamic models of the endtoend system must be obtained. Mathematical models that reflect both the driving physical phenomena as well as uncertainties present in the system will be established and validated along the project. These models will supplement nonlinear simulations and capture the complex dynamic interactions between the microvibration sources, the isolation system, the spacecraft structural dynamics and the optical payload system. With this knowledge, a second objective of the study is to demonstrate the capabilities of a common unified framework in which system design, robust controller synthesis, parametric sensitivity and worstcase analysis can be rigorously performed using a common set of wellestablished mathematical tools. These analytical tools provide strong stability and endtoend performance guarantees in the face of uncertainty without relying on timeconsuming Monte Carlo simulations. In a natural way, adaptive control solutions with guaranteed stability and performance margins will be obtained by design. Finally, the project will lead to the development of an advanced experimental testbed that will serve as a validation platform for future microvibration control and high pointing stability research activities.

Hurricane Maria Forecast Discussion Number 18

2017-09-20 16:40:55| National Hurricane Center (Atlantic)

Issued at 1100 AM AST Wed Sep 20 2017 000 WTNT45 KNHC 201440 TCDAT5 Hurricane Maria Discussion Number 18 NWS National Hurricane Center Miami FL AL152017 1100 AM AST Wed Sep 20 2017 The last radar image from the San Juan WSR-88D was received at 0950 UTC when Maria's eye was located only about 5 n mi off the southeastern coast of Puerto Rico. Subsequent 1-minute imagery from the GOES-16 satellite, as well as surface observations, indicate that the eye made landfall a little south of Yabucoa Harbor, Puerto Rico, around 1015 UTC. Now that the center is moving over the mountainous terrain of the island, the eye has become cloud filled, and the infrared satellite presentation has degraded. Without radar velocity data, the initial intensity is incredibly uncertain, but my best guess is 120 kt based on a typical inland decay rate. Maria's center is expected to move off the northern coast of Puerto Rico soon, and an Air Force Reserve reconnaissance aircraft is scheduled to intercept the center early this afternoon and provide a better estimate of how much Maria has weakened. The initial motion is northwestward, or 305/10 kt. This northwestward motion is forecast to continue for the next 48 hours, followed by a turn toward the north by days 4 and 5, while Maria moves between a mid-level high centered southeast of Bermuda and a broad trough extending from Tropical Storm Jose southwestward into the Gulf of Mexico. The track guidance is tightly clustered this cycle, and there were no significant changes made to the NHC forecast track. Once Maria moves off the coast of Puerto Rico, it will take some time for the structure to reorganize over the warm waters of the Atlantic Ocean. However, the shear is expected to be less than 10 kt for the next 24-36 hours, and Maria has an opportunity to restrengthen a bit over that time period. After 36 hours, a gradual increase in shear is likely to lead to a commensurate gradual decrease in the hurricane's intensity through the end of the forecast period. Since the SHIPS model, in particular, responds to the favorable conditions for intensification, the NHC intensity forecast lies just above the intensity consensus through much of the forecast period. Since we don't have radar imagery from San Juan, and the eye has become cloud filled in satellite imagery, the hourly position updates are being discontinued. KEY MESSAGES: 1. Maria's core is moving over Puerto Rico, with life-threatening wind, storm surge, and rainfall impacts continuing over the island. Everyone in Puerto Rico should follow advice from local officials to avoid life-threatening flooding from storm surge and rainfall. A Hurricane Warning remains in effect for the Virgin Islands, but conditions should gradually improve there later today. 2. Wind speeds atop and on the windward sides of hills and mountains and on high-rise buildings could be much stronger than the near-surface winds indicated in this advisory. 3. A Hurricane Warning is also in effect for the northern coast of the Dominican Republic, the Turks and Caicos Islands and the southeastern Bahamas, where Maria is expected to bring dangerous wind, storm surge, and heavy rainfall.

SUMMARY OF 1100 AM AST...1500 UTC...INFORMATION ----------------------------------------------- LOCATION...18.4N 66.5W ABOUT 15 MI...25 KM ESE OF ARECIBO PUERTO RICO ABOUT 25 MI...40 KM W OF SAN JUAN PUERTO RICO MAXIMUM SUSTAINED WINDS...140 MPH...220 KM/H PRESENT MOVEMENT...NW OR 305 DEGREES AT 12 MPH...19 KM/H MINIMUM CENTRAL PRESSURE...930 MB...27.47 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: The government of France has discontinued the Tropical Storm Warning for St. Martin and St. Barthelemy. The government of St. Maarten has discontinued the Tropical Storm Warning and Hurricane Watch for St. Maarten. The government of the Netherlands has discontinued the Tropical Storm Warning for Saba. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Hurricane Warning is in effect for... * U.S. Virgin Islands * British Virgin Islands * Puerto Rico, Culebra, and Vieques * Dominican Republic from Cabo Engano to Puerto Plata * Turks and Caicos Islands and the Southeastern Bahamas A Tropical Storm Warning is in effect for... * Dominican Republic west of Puerto Plata to the northern border of the Dominican Republic and Haiti * Dominican Republic west of Cabo Engano to Punta Palenque A Hurricane Watch is in effect for... * Dominican Republic from Isla Saona to Cabo Engano A Hurricane Warning means that hurricane conditions are expected somewhere within the warning area. Preparations to protect life and property should be rushed to completion. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area. A Hurricane Watch means that hurricane conditions are possible within the watch area. A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. Interests elsewhere in Hispaniola and the Bahamas should monitor the progress of Maria. For storm information specific to your area in the United States, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. For storm information specific to your area outside the United States, please monitor products issued by your national meteorological service. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 1100 AM AST (1500 UTC), the center of Hurricane Maria was located inland over Puerto Rico near latitude 18.4 North, longitude 66.5 West. Maria is moving toward the northwest near 12 mph (19 km/h), and this general motion with a gradual decrease in forward speed is expected through early Friday. On the forecast track, the center of Maria will move offshore of the northern coast of Puerto Rico during the next couple of hours. The center will then pass offshore of the northeastern coast of the Dominican Republic tonight and Thursday and then move near the Turks and Caicos Islands and southeastern Bahamas Thursday night and Friday. Maximum sustained winds are near 140 mph (220 km/h) with higher gusts. Maria is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Little change in strength is forecast during the next 48 hours, and Maria is expected to remain a dangerous major hurricane through Friday. Hurricane-force winds extend outward up to 60 miles (95 km) from the center, and tropical-storm-force winds extend outward up to 150 miles (240 km). The estimated minimum central pressure is 930 mb (27.47 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane and tropical storm conditions are occurring over Puerto Rico and the Virgin Islands. Tropical storm conditions are expected to begin in the warning areas in the Dominican Republic this afternoon, with hurricane conditions starting in the hurricane warning area tonight. Tropical storm conditions are expected to begin in the Turks and Caicos Islands and the southeastern Bahamas Thursday morning, with hurricane conditions starting Thursday evening. Wind speeds atop and on the windward sides of hills and mountains and on high-rise buildings could be much stronger than the near- surface winds indicated in this advisory. STORM SURGE: The combination of a dangerous storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water is expected to reach the following heights above ground if the peak surge occurs at the time of high tide... Puerto Rico...6 to 9 ft The deepest water will occur along the immediate coast near and to the north and east of the landfall location, where the surge will be accompanied by large and destructive waves. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances. For information specific to your area, please see products issued by your local National Weather Service forecast office. A dangerous storm surge accompanied by large and destructive waves will raise water levels by as much as 4 to 6 feet above normal tide levels in the hurricane warning area in the Dominican Republic, and 1 to 3 ft elsewhere along the northern coasts of the Dominican Republic and Haiti. A dangerous storm surge accompanied by large and destructive waves will raise water levels by as much as 10 to 15 feet above normal tide levels in the hurricane warning area near and to the north of the center of Maria for both the Southeastern Bahamas and the Turks and Caicos Islands. RAINFALL: Maria is expected to produce the following rainfall totals through Friday: Puerto Rico...12 to 18 inches, isolated 25 inches U.S. and British Virgin Islands...additional 5 to 10 inches, isolated 15 inches Northern and eastern Dominican Republic, Turks and Caicos and southeast Bahamas...8 to 16 inches, isolated 20 inches Northern Haiti...2 to 4 inches Rainfall on these islands will cause life-threatening flash floods and mudslides TORNADOES: Several tornadoes are possible over Puerto Rico and the U.S. Virgin Islands today. THE EYE: Do not venture outside when the calm eye of the hurricane passes over, as dangerous winds will return very quickly when the eye moves away. SURF: Swells generated by Maria are affecting the Leeward Islands, Puerto Rico, and the Virgin Islands. These swells will begin affecting the northern coast of Hispaniola, the Turks and Caicos Islands, and the Southeastern Bahamas during the next day or two. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next intermediate advisory at 200 PM AST. Next complete advisory at 500 PM AST. $$ Forecaster Berg
