107
While we waited for the replacement receiver to arrive we decided to start studying for a 107 license. A 107 license is needed to operate a sUAS (small Unmanned Aircraft System) or “drone” for commercial purposes. We are unsure if this license is needed, but as it also allows greater freedom in sUAS operation we…
What is a high altitude balloon? (Part 1)
High Altitude Balloons (HABs) are manned or unmanned balloons that are used to carry payloads into the stratosphere. HABs are capable of reaching altitudes of 18-53 km (11-32 mi) above sea level. HABs are filled with lighter than air gas. It is this gas, that gives them their lift. Once filled, the HAB is released,…
More Testing
With the Parachute System Control Computer (PSCC-2) fully programed and functioning, we had reached the point where we could perform an immediate drop test. But, there was one more test we wanted to do before we staked the payload and all of it’s electronics on the performance of the PSCC-2. In preparation for the test…
Starting Again
The most recent test of the Parachute System Control Computer (PSCC), which is designed to automatically deploy the parachute during decent ended in failure. Not only did the PSCC display once again a concerning lack of reliability but, as it did not deploy the parachutes in time, it and the Parachute Test Payload (PTP) that…
Impact
After the results of our last tests, we were feeling confident that the PSCC (Parachute System Control Computer) was approaching a functional sate. During our latest in a series of tests, all aspects of the PSCC code worked as expected, with the only issue being a recurring discrepancy in the GPS and air pressure altitude…
Preparing for Flight
Our original plan was to perform our first drop test of the parachute system on the 20th of December. The three failures of the parachute system print jobs (more about this here) used up much of our time, but we still had one more week before this deadline. To achieve this goal, we had many…
what a cool video
