Anew satellite carrying hyperspectral imaging payloads will be able to determine its position in real time to sub-decimetre accuracy, thanks to an in-orbit demonstration of new technology.

Loft Orbital’s small YAM-2 satellite is carrying Fugro’s SpaceStar GNSS Precise Point Positioning system, which receives precise GNSS real-time orbit and clock corrections from geostationary satellites.

According to Fugro, highly accurate positioning in LEO is becoming more important for earth observation applications, satellite constellation management and debris collision avoidance.

“We’re especially excited to demonstrate this new functionality,” said Loft Orbital CTO, Pieter van Duijn.

“Fugro’s SpaceStar service is something that can really help not only Loft Orbital’s missions but also be of interest to the wider application of space situational awareness and safety.”

YAM-2 was launched on 30 June into a 525-km-altitude sun-synchronous orbit from Cape Canaveral in Florida aboard a SpaceX Falcon 9 rocket.
