Ideal For: S-Band Prototyping


Transmitting and Receiving made simple with the Adalm Pluto.


A full duplex radio in this kit makes demoing your communications systems simple, and connecting with satellites a seemless venture. The Standard Bowshock GS kit allows for reliable comms prototyping and the potential to bounce off repeater satellites, or run mission operations for your own.


Get started communicating with satellites and other objects in orbit today! You can communicate to the International Space Station, search for amateur satellite beacons, or pull telemetry off the latest SpaceX launches. FCC Licensing and/or Technical License for Amateur Operation may be required in the USA to transmit. Other countries check their local regulatory codes.


The Standard Bowshock GS kit is designed to be built by the beginning small satellite engineer. Some technical skill in electronics and hand tools is necessary. The kit includes a 9 element yagi antenna centered in the UHF region, an Adalm Pluto for transceiving, and a SatNOGs rotator for tracking. More information about the rotator can be found here:


Mission operators may consider upgrading the radio with a GPS signal source and power amplifier, along with bandpass filters to increase link budget and filter out noise and harmonics. More instructions can be found in the documentation pages for the Adalm Pluto


The yagi can be upgraded to dish and feed with counterweight if desired. The total mesh dish size should be kept under 3ft and wind weather conditions checked to ensure rotator components are not damaged.


This platform is excellent for learning, but for those that want to squeeze a few extra decibals out of their set up, check out the Advanced Bowshock GS Kit.
