The Flight of a Brave Squirrel I spent time cleaning up the FS1 Telemetry data and turned it into and Excel spreadsheet and the following graphs. The FSQCal program we used to decode the FS1 telemetry will record all the perfect message packets into the file fs1.txt as part of the protocol, […]
A quick Synopsis More details will follow after I can clean up the data, but here are the flight statistics collected from the balloon telemetry. The flight was a lot of fun and a success! Flight Quick Stats Launch Date 201-1-16 Time of lift-off: 19:24 UTC 11:24 AM PST Launch Location: Anderson Dry […]
The FS#1 flight controller is designed to measure basic weather information (Barometric Altitude, Air Pressure and Temperature) and relay that information periodically to the ground via radio telemetry using the FSQ protocol. Additionally, the flight controller conserves battery power by turning off the radio and weather sensor between transmissions. In a nutshell the […]
Meet our intrepid explorer Flying Squirrel One. This very brave explorer will be the first Squirrel Engineering project to be launched in to the upper atmosphere lofted by nothing more than a 36 inch Helium filled party balloon. During the flight, our explorer will dutifully report temperature, air pressure and altitude back to mission control […]
The Mission Before I can describe the flight software I need to make clear what the specific mission goals of Flying Squirrel #1 (FS#1) are. The software design is based upon these goals and an understanding of the goals will make the software easier to understand. In a nutshell the goal of FS#1 is to […]
The flight controller of Flying Squirrel #1 is the brains of the flight. The controller will measure the environment around the balloon, format the data into a Telemetry message and transmit the telemetry signal back to the ground using the chosen protocol (FSQ) for the flight. The flight controller will also manage the power to […]
To get the telemetry signal on the air an antenna is needed. By necessity, the antenna must be light weight and simple. The size of an antenna is determined by the frequency we need the antenna to work at. The lower the frequency, the larger the antenna will be (There are exceptions to this rule […]
Now that I have a list of protocols and a general plan to transmit telemetry on the 20 meter Ham bands, how do I get “on the air”? This post will describe the transmitter hardware for the telemetry system. Generating Radio Frequency – There is a board for that. After a lot of searching an […]
What’s the frequency Kenneth? The big unknown for me, at least at the start, is how am I going to know where the balloon has traveled. I need to be able to send radio telemetry from the balloon back to the ground somehow. My stated project goal that the balloon be capable of global circumnavigations, […]
