VELOX C1 [NTU]

The VELOX-C1 mission is a Singaporean experimental microsatellite mission to study tropical climates.

VELOX-C1 will use of a special technique known as radio occultation and advanced algorithms, to obtain weather data such as the upper atmospheric temperature, humidity and pressure, which are useful for long term climate studies. Radio occultation makes use of the radio signals transmitted from the GPS satellites 20,000 km above the Earth. Using specially-designed GPS receivers, VELOX-CI can detect these signals for a short duration, even if there is no line of sight due to the bending of these signals by the atmosphere.

The payload consists of:

• GPS Occultation (primary experiment)
• Experimental RF Probe
• Other experimental missions: e.g. Altitude determination with GPS

VELOX C1 is scheduled for launch in Q4 2015 as a secondary payload on an Indian PSLV-CA launch vehicle and will be flying in a near equatorial orbit of 550 km altitude with around 15� inclination.
