Stellar Exploration
focuses on affordable hardware development for miniaturized aerospace systems, with a proven track record of working solutions for operational deployment.
Products Overview
High-quality aerospace solutions for military, civil and commercial customers. We have delivered several nanosatellite propulsion, power, and RF tracking subsystems, as well as rich experience in satellite integration, solid rocket propulsion, and more.
Power subsystem
The nanosatellite power subsystem was developed in response to unique requirements for high peak current with long lifetime (>3 years), at low unit cost. The subsystem includes redundant lithium-ion modules with dedicated balancing and control for each string (in order to maximize lifetime). It can provide up to 5 kW peak power for 90 seconds every orbit, with the projected lifetime exceeding three years. The integrated subsystem includes programmable charging and discharging control, failure detection and isolation, multiple watchdog timers, and power-on-reset capability. It can be scaled to provide up to 500 W/kg peak power.
The power subsystem has flight heritage with >24 units launched from 2018 to 2021.
We can modify the battery to fit your needs. CONTACT US TODAY FOR A QUOTE.
Lead time: 4-6 months
nano satellite Mono & bipropellant propulsion
As part of early R&D for a NASA funded deep space nano-satellite mission we have designed, built, and tested a miniaturized hypergolic bipropellant thruster. It provides 3 N of thrust with 285 sec specific impulse. The propellant is pressurized with gear pumps, allowing for precise propellant metering and low pressure tank design. Our in-house propulsion system controller board design leverages the state of the art in BLDC motor control, and includes hardware for all of the necessary sensors and actuators. Contact us to find out how we can help add propulsion to your next mission.
passive nano satellite tracking and telemetry tag
The tag is truly low-cost passive device similar to a RFID tag that can be attached to all small satellites. Using backscatter modulation from space radars, the RF tag can communicate satellite telemetry. Due to the nature of the device, it has absolutely no risk to host satellite and range safety. The tag relies on passive energy harvesting and thus requires no harnessing, deployment or release switches. Overall the design is low cost and robust throughout the lifetime of the object under tracking.
Lead time: 3 months
