Microsatellite platforms provide mission designers with pre-designed options for systems that can speed up missions. In this article we share details on a variety of different microsatellite buses and platforms available on the market.
Please note this is a fast-moving industry segment and we will be keeping this article up to date when new products come to market, or older sysems become obsolete.
Introduction to microsatellite platforms
Microsatellite platforms are pre-designed satellite systems featuring various subsystems, structural elements, and electronics to enable primary payloads to be integrated faster and with greater ease than creating a completely bespoke system.
They are often also referred to as buses and can bring various interesting new capabilities to engineers developing microsat missions and services.
There is significant variation in the masses and volumes of microsatellite platforms available on the market. You should carefully consider the performance and redundancy requirements of your mission or service against the cost of a larger system, to assess the overall potential return on investment (RoI) that is expected.
In addition, every mission team has a different set of specialist skills, so it is important to determine what sort of integration, calibration, and testing requirements each microsat platform has in order to determine the best system for your needs.
Aside from these characteristics, here are some of the other factors that need to be considered when selecting the right microsat bus for your needs:
- Available Size, Weight and Power (SWaP) budget
- Supplier location (e.g. for export controls purposes)
- Technology Readiness Level (TRL)
- Connectors and interfaces included
- Costs and lead time, considering achievable return on investment (RoI)
- Post-sales support and troubleshooting options
- Regulatory compliance considerations
- Any incorporated data standards or operating protocols
- Flexibility to rearrange the hardware included in the bus, if required
- Redundancies and contingencies onboard
Microsatellite payloads and technologies are bringing some powerful new capabilities to many different segments of the space industry. Utilizing a pre-integrated (and often pre-qualified) platform could be the ideal choice to accelerate the development of your mission.
You can find more such advice, as well as details on both microsat and CubeSat platforms, in this article. In the next section we share information on variety of microsatellite platforms on the market.
