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

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

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.

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 2007 - 5 year mission 25 Products Feed into InfoTerra to satisfy wide-ranging commercial market place. Possible ESA involvement

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 Funding level- not strategic

RAPIDS 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 The trailer towed by a Land Rover, which contains local image processing and visualisation facilities. RAPIDS has already been demonstrated with ERS and SPOT.

Current Status Launched successfully on a Cosmos rocket 27 October 2005. [07:52 BST] Telemetry received on 1st UK pass Orbit altitude 686km, 1045 LTAN Commissioning complete – all main functionality proven Ops underway – delivering images to users

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
