MXL students and Aerospace Engineering staff are spending this week at the Peach Mountain dish performing annual dish maintenance and prepping for upcoming proof of concept testing. The maintenance includes greasing all the bearings and gears. A software-defined radio and UHF antenna will then be installed in the feedhorn in order to test the ability to track and decode satellite transmissions. MXL’s RAX-2 satellite will be used initially as the signal source for testing.
