Images coming soon.
We will start with the balloon and work our way down.
The first piece of equipment in the payload train is the parachute. It has an 8 ft diameter and a mass of gm.
The next items are the communication transponders. We have two that are independent of each other. They both have their own gps units and power supply. This reduces the chances of total communications failure. The first uses a Byonics MicroTrak FA 8000 transponder coupled with a EM-408 GPS module from USGlobalSat. The MicroTrak transmits on 143.390 MHz and the gps unit works very well at high altitudes. Our highest reading was from 95 k ft.
The second transponder is also from Byonics and is based around the MicroTrak as well. But this unit is called the "All in One" (AIO). It ships with a gps unit and MicroTrak on one board and comes in it's own case. The AIO is a simple "flip the switch" tracker. Unfortunately there is a limit on the unit that puts a operational ceiling of around 50 - 60 k ft. So the AIO will loose tracking above this level and regains tracking ability once it falls below this level.
Next down the train is the imaging equipment. We use a Pentax Optio W30 waterproof camera for stills. It takes good images at 7.1 Mp. The appeal of this camera was it's built in interval shooting. We usually have the camera take a shot every 10 sec.
We use a GoPro Hero 4 Black for digital video.
We have recently purchased a SPOT Trace for tracking. It works very well and can be used with the SPOT APP on a smart phone to track.
Additionally, we are using a NAL Iridium 9602 LP Satellite Modem for redundant tracking capabilities and two way comm.
The last items on the train are the experimental modules. These are custom designed by the students to fit the needs and design requirements for the experiments going aloft each year. Last year the students designed a dodecahedron.
