1 BNSC Agency Report Wyn Cudlip BNSC/QinetiQ to WGISS22 Annapolis, September 2006

2 CEOS WGISS 22 Meeting, Annapolis September, 2006 BNSC Instruments/Missions Current Instruments –ATSR2 on ERS-2 –AATSR on Envisat –CHRIS on Proba –Disaster Management Constellation Small Satellites –TopSat – launched October –http://www.qinetiq.com/industries/space/spacecraft_technology/case_study_topsat/ Planned Medium Satellites –TerraSAR L-Band

3 CEOS WGISS 22 Meeting, Annapolis September, 2006 PROBA Project for On-Board Autonomy ESA mission (on Indian Launcher in 2000) Platform technology demonstrator 615 km sun synchronous orbit. Free ride for: –CHRIS - Compact High-Resolution Imaging Spectrometer –SREM - Radiation measurement sensor –DDEBIE - debris measurement sensor –Wide angle Earth pointing camera –Star tracker and gyroscope

4 CEOS WGISS 22 Meeting, Annapolis September, 2006 CHRIS Compact High-Resolution Imaging Spectrometer operates from 400 nm to 1050 nm 14km swath 63 bands at 36m resolution –or 18 bands at 18m resolution Science Team include: –University of Swansea –ESSC, University of Reading –University of Plymouth

5 CEOS WGISS 22 Meeting, Annapolis September, 2006 Disaster Management Constellation (DMC) 32m res., 600km swath. 5 satellites in orbit; can provide daily coverage – UK, Algeria, Turkey, Nigeria, China Surrey Satellite (SSTL) Platform.

6 CEOS WGISS 22 Meeting, Annapolis September, 2006 TerraSAR L-Band Working in tandem with German TerraSAR X-Band X-band: 1-3 m res.; twin polarisation. L-Band: 5m res.; multi-pol –(HH, HV, VH, VV). Launch year mission 25 Products Feed into InfoTerra –to satisfy wide-ranging commercial market place. Possible ESA involvement

7 CEOS WGISS 22 Meeting, Annapolis September, 2006 TopSat Summary Optical imagery (at Nadir) with Ground Sampling Distance of –2.8m pan (17 x 17 km) –5.6m multi-spectral (12 x 12 km) Sun-synchronous orbit (686km) Low cost demonstrator (20M$) Launched 27 October –All main technical objectives achieved Data download to mobile antenna

8 CEOS WGISS 22 Meeting, Annapolis September, 2006 Trailer TopSat tracking and data reception 2.7m antenna 2 hours set up time Very rapid downlinking to user – data on ground within 2 minutes of imaging RAPIDS The trailer towed by a Land Rover, which contains local image processing and visualisation facilities. RAPIDS has already been demonstrated with ERS and SPOT.

9 CEOS WGISS 22 Meeting, Annapolis September, 2006

10 Launched successfully on a Cosmos rocket 27 October [07:52 BST] Telemetry received on 1 st UK pass Orbit altitude 686km, 1045 LTAN Commissioning complete – all main functionality proven Ops underway – delivering images to users Current Status

11 CEOS WGISS 22 Meeting, Annapolis September, 2006 Atlantic City, New Jersey

12 CEOS WGISS 22 Meeting, Annapolis September, 2006 Atlantic City, New Jersey

13 CEOS WGISS 22 Meeting, Annapolis September, 2006 Central London

14 CEOS WGISS 22 Meeting, Annapolis September, 2006 Central London

15 CEOS WGISS 22 Meeting, Annapolis September, 2006 TopSat Follow-on Concepts TopSat Plus: Similar resolution to TopSat demonstrator; greater imaging size, capacity, accuracy & greater lifetime TopSat Enhanced: Pushing towards limit of current camera design, and lowering altitude to achieve 1.65m resolution (pan). TopSat One Metre: Aspiration to achieve 1m resolution with low cost spacecraft – subject to developments in lightweight optics and structures Low costs supports constellations to give high timeliness
