Mission Details

HXMT

HXMT (Hard X-ray Modulation Telescope) is a collimated hard X-ray (20-200 keV) telescope with high sensitivity and spatial resolution. It is a collaboration between institutes in China (which will provide the spacecraft and main hard X-ray imager) and the UK (which will provide low and medium-energy imaging instruments).

Sun-Synchronous Orbit

ÑuSat 3

The Argentinian ÑuSat earth observation satellites form the Aleph-1 constellation developed and operated by Satellogic S.A.

The satellites in the constellation are identical 51 cm × 57 cm × 82 cm spacecraft of 37.5 kg mass. The satellites are equipped with an imaging system operating in visible light and infrared. The constellation will allow for commercially available real-time Earth imaging and video with a ground resolution of 1 m. The satellites were developed based on the experience gained on the BugSat 1 (Tita) prototype satellite.

A U/V transponder with 2 W of output power for 8 GHz downlink and 2 GHz uplink will be operating on 100 kHz bandwidth. For backup telemetry, designers are considering UHF transponder operating at 9k6 GFSK.

Sun-Synchronous Orbit

Zhuhai-1 OVS 1A & 1B

The Zhuhai-1 earth observation satellites are the video component of the Chinese Orbita earth observation system by Zhuhai Orbita Control Engineering Ltd.

Two OVS-1 satellites will constitute the prototype OVS-1 video component. The operational Orbita constellation is to consist of ten video satellites (OVS-2), hyperspectral satellites (OHS-2), and small personal satellites (OPS-2).
