Avionics

Peregrine’s avionics achieve terrestrial computing speed with high reliability. Rugged, radiation-tolerant computing enables autonomous landing and safety in the demanding space environment.

Structure

Peregrine’s structure is stout, stiff, and simple, allowing for easy payload integration. The configurable decks and enclosures accommodate payload-unique mounting and placement. Rover missions release from the underside of the deck, while BUS elements are housed inside the enclosures. Four legs absorb shock and stabilize Peregrine on touchdown.

Propulsion

Peregrine uses a propulsion system featuring next generation space engine technology. Its five main engines perform all of the spacecraft’s major maneuvers, including trans-lunar injection, trajectory correction, lunar orbit insertion, and powered descent. Four clusters of attitude control thrusters maintain lander orientation throughout the mission.

Communications

Peregrine uses a high-powered, flight heritage transponder and a combination of low and medium gain antennas to relay data between the payload customer and their payload throughout the mission. The lander-payload connection is provided via Serial RS-422 or SpaceWire for wired communications and a WLAN modem for wireless communications with deployed payloads such as rovers.

Power

Peregrine provides 28 volt operational and heater power to payloads throughout the mission. It uses a panel of triple-junction solar cells to generate power and a space-grade lithium-ion battery to store energy. The solar panel is pointed towards the Sun whenever possible to provide continuous power generation, while the battery is utilized when the Sun is not visible or for quick discharge activities.

GUIDANCE NAVIGATION & CONTROL

Peregrine’s GNC system uses heritage algorithms enhanced by recent developments in machine vision navigation. Off-the-shelf sensors and standard techniques provide reliability during cruise and lunar orbit, while Doppler LiDAR and Astrobotic’s proprietary terrain relative navigation (TRN) provide unprecedented precision during descent and landing. A scanning LiDAR can also be added to detect and avoid slopes, rocks, craters, and other hazards during landing.
