ECONOMICAL RIDESHARE

Excelsior shares a common EPS architecture with the larger spacecraft in the product line while providing redundancy in key components. Terran Orbital’s entire line of satellite buses shares the same avionics and GNC algorithms.

The Excelsior allows maximum payload volume and a large solar array while providing low launch costs. This class also gives it a power advantage over the nano platforms. It includes a propulsion bay accommodating EP, Hydrazine, or a mix of propulsion systems.

Terran Orbital employs top-of-the-line automation and modern manufacturing processes to support the delivery of hundreds of buses annually. From order to launch, in quantities from one to a constellation of one hundred, Terran Orbital accelerates the delivery of mission solutions.

KEY BENEFITS

Build-out constellations faster with the ability to launch two satellites per ESPA port
Delivers higher power-to-payload ratio than nano-class platforms
