Astranis unveils Perceptor, a GEO space-surveillance scout

Astranis announced Perceptor, a geostationary-orbit surveillance spacecraft built on its microGEO platform to observe and inspect other satellites and reposition via electric propulsion, marking a move from broadband to space-domain awareness. The system can fly by other satellites and operate in coordinated groups, helping military and commercial operators reduce surveillance blind spots in GEO as the Space Force pursues next-generation surveillance under RG-XX; the announcement follows a recent $450 million funding round to scale manufacturing for government procurements.

"Satellite Manufacturers Address Challenges in Shrinking GEO Market"

Satellite manufacturers at the Satellite 2024 conference defended the diminished market for traditional geostationary communications satellites, acknowledging a significant drop in orders but insisting that demand for such spacecraft is not disappearing. They attributed the decline to market adjustments and emphasized the evolving role of GEO satellites in multi-orbit solutions, highlighting technological innovations and the business case for GEO satellites. The panel also discussed shifting market dynamics, greater collaboration with government customers, and the potential resurgence of larger GEO satellites in the future.

"Rising Claims: Space Insurers Prepare for Propulsion Issues on Four GEO Satellites"

Insurers are bracing for more claims as four satellites, including Yahsat's Al Yah 3, Avanti Communications' Hylas 4, and Northrop Grumman's two Mission Extension Vehicles (MEV-1 and MEV-2), experience propulsion problems due to issues with their onboard Power Processing Units (PPUs). The PPUs, provided by Aerojet Rocketdyne, supply electrical power to the thrusters needed for station-keeping in geostationary orbit (GEO). The workaround of reducing voltage to the remaining PPUs has prevented complete failure but will impact the satellites' design life. Insurers are already facing over $800 million in losses this year, and the propulsion issues are expected to result in at least $50 million in additional claims.
