DEF

[An antenna] equipped with distributed transmit/receive modules which provide distinct transmit and receive beams.

CONT

The most significant difference between RADARSAT-2 and RADARSAT-1 payload technology is that RADARSAT-2 uses a fully-active phased array antenna, rather than the passive slotted waveguide antenna used by RADARSAT-1. Fully-active phased arrays offer a number of very significant benefits over passive antenna, but they also add great complexity.... The phased array is made up of 512 individual radiating elements, organized into 16 columns(picture below shows a single column) along the 15-metre antenna length, each with 32 rows across the 1. 5-metre width. The phase shifters and amplitude control are built into the Transmit/Receive(T/R) modules, which feed the radiating elements. Each column has a computer that controls the 32 T/R module settings and these 16 computers are all linked to another computer(in the spacecraft bus) that orchestrates the overall antenna behaviour.

active array antenna: term officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).

Launch and early orbit phase. The launch phase involves a series of delicate operations not only for the... launcher, but also for the fully-assembled satellite... The launch phase... ends 18 minutes and 25 seconds after lift-off when the satellite separates from the launcher. The satellite, controlled by its onboard computer, then begins a series of automatic operations known as the "acquisition sequence". At the end of this sequence, the payload instruments are pointing earthward and the satellite's internal configuration is very close to that required for routine operations.

CONT

Extra Vehicular Activity Radiation Monitor ... The purpose of EVARM is to carry out flight experiments to investigate and characterize the doses received by different parts of an astronauts body (e.g., skin, eyes, and blood-forming organs) during an EVA. The doses will be analyzed with respect to the time and position of the EVA as well as the orbit, altitude, and attitude of the Station. A relatively new type of electronic radiation dosimeter, the Metal Oxide Semiconductor Field Effect Transistor (MOSFET) will be used to collect dose measurements.

CONT

EVARM is designed for use with the NASA Extravehicular Mobility Unit, or spacesuit, worn by both Space Station and Space Shuttle crewmembers during Station operations. The experiment consists of a storage/badge reader unit and 12 badges-a set of three each for up to four spacewalkers. The sets are designated EV-1, EV-2, EV-3 and EV-4, corresponding to the designation of each potential spacewalker. When not in use, the badges are placed in the storage-reader box, which is stored in the Human Research Facility payload rack. The badge contains a silicon chip specially designed by Thomson-Nielsen-called a Metal Oxide Silicon Field Effect Transistor(MOSFET)-that continuously measures total radiation dosage and a connector that plugs into the badge reader. The reader that can download badge is shown placed in a pocket in the lower left leg of an astronaut liquid cooling garment. Badges also are placed in the front torso and fabric communications cap of the spacesuit undergarment(NASA/JSC). During normal operations, the Station crew will record the background radiation dosage on each badge and transmit it to the ground every week. Shortly before a spacewalk by Station or Shuttle crew members, the crew will measure the radiation dosage of each badge to be used in the spacewalk. A set of three badges will be inserted into pockets sewn into the front torso and front leg areas of the liquid cooling undergarment and the top of the fabric communications cap of each spacesuit. Those locations were selected because of the radiation hazard to sensitive soft tissues such as eyes and internal organs, as well as the hazard to the skin on the arms and legs, which are not as well shielded as the torso. Shortly after the spacewalk, the crew will plug each badge set into the badge reader. They will later transfer the data to the Human Research Facility laptop computer for transmission to the payload team on the ground.

Three MALDs can be carried on a stores pylon, compared with one ITALD or comparable decoy drone. The MALDs can be programmed to fly formations simulating those of combat aircraft, such as the classic lead and wingman arrangement. The course of a MALD can be programmed by displaying a digital map on a computer and then using a mouse to click on the appropriate map "waypoints", and the "wingman" can then be programmed to follow the same course with an offset. The MALD's computer will be able to follow a large number of waypoints over a 460 kilometer(286 mile) course. It will also be sophisticated enough to simulate maneuvers typical of attack aircraft.
