Rocket tracking is always recommended to make your projects easier to locate after landing. Tracking can range from inexpensive beepers that aid in locating, to comprehensive GPS tracking systems. This page will provide links to different types of vendor tracking systems, as well as a running list of frequencies that are currently in use. Please note that many tracking systems require an amateur radio license, however there are a number of choices that do not. The lists below include both.

RDF – basically radio beepers, and you follow the signal strength with a directional antenna

In case you are considering radio-based tracking, you might want to try to avoid frequencies that others use. Its not critical, as they won’t be in use all the time, but if you have choices, it might be good to select one that is not used. Please let me know to add your frequencies to the list.
