About
Ambassador comes with Terran Orbital’s standard mini-satellite EPS architecture and builds off the entire product line of spacecraft platforms with the same avionics and GNC algorithms. The reaction wheels on the Ambassador are sized to allow the spacecraft to maintain agility, and the platform is designed from the ground up to be compatible with rideshare requirements. Ambassador supports commercially available or custom payloads and offers optional Type 1 encryption for military-grade security. It includes a propulsion system ideal for phasing a constellation into its mission orbit, station keeping, and disposal. The precursor to the Ambassador (Zuma+) was designed for the Space Development Agency’s Tranche 1 Transport Layer.
Key benefits: the largest deck area allowed by an ESPA-Grande interface for rideshare missions; top offering for the DoD/Intel community with the largest available payload and optional Type 1 encryption.
Baseline modules included: Flight Computers (2), Watchdog Backplane, 66V Battery Modules (8-12), 66V MPPT (2-3), 66V Load Controller, 28V Low/High-power Point-of-Load (varies), Coarse Sensors (4), Gyro Assembly, Star Trackers (3), GPS (2), Magnetorquers (3), Reaction Wheels (4), LDRR (2), MDR (2).
