Please explain in the area below why an STA is necessary:
The applicant seeks a STA to operate test transmitters to conduct channel sounding measurements in two Amateur Bands. This experiment will gather radio propagation data to address future Position Navigation and Timing (PNT) challenges. Software defined radio (SDR) transmitters (Great Scott Gadgets HackRF One) will be used to generate test waveforms. These waveforms will utilize BPSK coding and will have occupied bandwidths between 100 Hz and 400 kHz. Data recorded by receivers will be analyzed to inform on interference, multipath, and other propagation impairments.

Purpose of Operation
Please explain the purpose of operation:  Experimental program to perform channel sounding measurements over Amateur Bands. Each experiment will be only hours in duration, and multiple experiments will take place ofer the specified months of operation. Continuous operation over this time period is not expected.

Callsign: WM9XBK
Class of Station: MO
Nature of Service: Experimental

Requested Period of Operation
Operation Start Date: 06/04/2018
Operation End Date: 12/04/2018
