Power subsystem

The high power nano satellite 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 cells with dedicated balancing control for each string (in order to maximize lifetime). It can provide up to 5 kW peak current for 90 seconds every orbit, with the projected lifetime exceeding three years. The integrated subsystem includes the programmable charging and discharging control, failure detection and isolation, multiple watchdog timers, and power-on-reset capability. It can provide up to 500 W/kg peak current, with validated lifetime of year years.

The power subsystem has flight heritage with multiple units launched in 2018/19

nano satellite 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
