Problem
Small satellite developers often face long lead times, high costs, and limited reliability when integrating custom spacecraft mechanisms for tasks such as thruster pointing, antenna alignment, or optical payload orientation. Traditional mechanisms can be bulky, power‑hungry, and require extensive design and testing effort, constraining mission flexibility and schedule.
Solution
Propel Space provides volume‑efficient, plug‑and‑play spacecraft mechanisms that address these constraints. Their flagship PM‑5 2‑axis gimbal delivers ±20° motion for thrusters, antennas, and optical payloads while weighing under 1.25 kg and consuming less than 10 W, with an integrated launch lock for on‑orbit safety. The company offers a standardized, low‑mass solution that shortens procurement cycles and reduces overall mission cost. In addition, Propel Space supplies comprehensive design, analysis, systems management, and testing services to accelerate development and ensure reliability throughout the satellite lifecycle.
Target Audience
Primary customers are small‑sat manufacturers, payload integrators, and mission developers who need reliable, low‑mass pointing mechanisms and associated engineering support to meet tight schedules and budget constraints.
