The Personal Satellite by Italian aerospace inventor Giuseppe Talarìco is a 38 x 42 mm three-board sandwich that is compact enough for 100 units to fit into the same package as the typical cube satellite (CubeSat) deployer for 1% the unit cost of a space satellite deployment – 1000 Euros is typical for a single CubeSat launch as of 2023 – with significant improvement in the odds of successful missions per launch thanks to the sheer number of units deployed.
Additionally, the compact form factor and decaying low-Earth polar orbit after launch – starting at approximately 250 km above the Earth’s surface – means that each satellite will burn up on re-entry, eliminating worries of any contribution to the growing space debris problem. The typical lifetime for each Personal Satellite ranges from 2-3 weeks to 2-3 months at a maximum for applications that include commercial and academic research efforts and short-term radio deployment projects.
The three boards that comprise each Personal Satellite are as follows:
- Motherboard: MCU + LoRaWAN via the TTN network for global data transmission and device monitoring without the requirement for a dedicated terrestrial base station – TTN allows users to access their satellite via the internet thanks to a network of LoRa gateways across many countries.
- Payload board: This board contains your choice of mission-critical sensors and other circuitry, for example to measure UV levels or other conditions in the upper atmosphere.
- Power board: This contains the required circuitry for powering the satellite using harvested solar energy or an on-board battery.
Since the satellites are placed in an orbit that does not offer GPS coverage, an onboard motion-sensing SoC (LSM9DS1) can be used to track its position during the mission thanks to a plot of the 3-axis-acceleration, gyroscopic-velocity, and magnetic-field data picked up by this sensor.
