These included the Energetic Particle Telescope (PET), a new radiation monitoring sensor, and HERMOD (High Density Space Form Connector Demonstration), testing multi-line optical fibre reliability in space. A number of demonstration modules were also included on PROBA-V. An S-band Telemetry, Tracking and Command (TT&C) mode is used in conjunction with an X-band data downlink subsystem. The satellite bus was built on the heritage of the PROBA-1 and PROBA-2 missions, with only the on-board switching (OBS) receiving minor modifications. It had an orbital period of 101 minutes and an inclination of 98.64°. PROBA-V operated in a sun-synchronous orbit with an altitude of 820 km, which decayed over time due to the lack of any on-board thrusters. PROBA-V measured across four spectral bands: blue, red, VNIR (visible near infrared), and SWIR (shortwave infrared). Each telescope had an individual spatial resolution of 300 m, yielding a 100 m resolution across the central telescope. Accounting for cloud cover, this corresponded to a full sweep of Earth’s vegetation every 10 days. Performance SpecificationsĮach TMA was a multispectral pushbroom spectrometer, observing the surface with a swath width of 2250 km, a noticeably large value for a satellite of PROBA-V’s size. Each SI contained one three-mirror anastigmat (TMA) telescope, and a beam splitter to divide up separate visible, near-infrared (VNIR) and short-wave infrared (SWIR) spectral bands.Īlongside each telescope, the optical bench also carried star tracker optical heads allowing for precise co-alignment, and a radiator to remove excess heat from the optical system. PROBA-V’s Field of View (FOV) is constructed from three Spectral Imagers (SI). The primary payload was the Vegetation Instrument, a multi-spectral radiometer, built by Belgian satellite specialists, Optronic Instruments & Products (OIP) systems.
