Telemetry Checks

On day 2, electrical testing continued. With the instruments installed in the rocket, it was time to test the telemetry and power systems. The team is happy to report that once again everything went smoothly.

First Day on the Range!

Today the GREECE team made the trip out to Poker Flat Research Range for day 1 of the campaign. After signing in (and remembering to plug in the car!) we got to work unpacking our instrument and running preliminary tests.

Payload Assembly Building at PFRR

For the first two weeks the team will mostly be working in the Payload Assembly Building, where we will do most of the electrical checks and put together the various sections of the rocket.

For our initial test, we turn the instrument on before it gets installed in the rocket and check that the data from all the sensors looks good. In the picture above, the back left are our Langmuir Probe and magnetometer. These measure currents and magnetic fields, respectively. On the right are the quad stacers. They aren’t fully assembled in this picture, but for the launch there will be four metal spheres which measure voltages. Front and center is the electronics box, which collects data from all the sensors, performs some signal processing, and then sends the data to the telemetry section of the rocket to be transmitted back to us on the ground. All systems were nominal – the Fields instrument had survived the plane ride intact.

With the initial bench testing complete and successful, the team finished the day by installing the instruments in the payload section of the rocket. A good end to a busy first day!
