Give the following information of person who can best handle inquiries pertaining to this application:   Last Name: Eigenberg First Name: Eric Title: Flight Operations Lead Phone Number: 6059291497

Explanation

Please explain in the area below why an STA is necessary: The STA is necessary to operate transmit testing equipment in support of the development of a communication MESH network for high-altitude balloon systems. The transmitter will be utilized by a mobile networked MIMO (MN-MIMO)

Purpose of Operation

Please explain the purpose of operation:

The purpose of the operation is to conduct high-altitude balloon testing using the mobile networked MIMI(MN-MIMO) radios in the Kermit TX area. The ground station with be a land based mobile platform in place for the duration of the balloon flight only and will be used to monitor the health and telemetry of the system and to maintain positive control for safety of the flight operations. The link will allow us to transmit command and control messages to the flight control unit as well as monitoring information from the balloon including high rate telemetry, navigation details and flight termination data necessary for coordination with the FAA ATC and ARTCC centers
