Transmitting equipment is manufactured by Microhard Systems Corporation, Free Wave Technologies, Advanced Microwave Products, Global Microwave Systems, and Microair Avionics.
FCC staff has asked for several items of information before approving the application. The FAA operates in the frequency bands 328.6-335.4 MHz, 1090 MHz, and 1215-1390 MHz; FCC staff asks for coordination of these bands with the FAA Regional Office. In addition, the frequency bands 225-328.6 MHz and 335.4-399.9 MHz are used for military purposes, and the applicant was asked to coordinate with NTIA’s Interdepartment Radio Advisory Committee (IRAC).
AAI/Textron Systems Corporation also filed an application (with supporting exhibits) for special temporary authority to operate on 420-450 MHz and 2000-2400 MHz for a government project apparently involving the Orbiter miniature unmanned aircraft system.

One application seen for this system is video image enhancement for television broadcasting of automobile racing events. The would allow television viewers to see, displayed on screen, the real-time location of cars during a racing event.
The vehicles would be equipped with GPS receivers and other sensors that generate a data packet every 200 milliseconds. The wireless system would collect those packets and deliver them to a control station in real time. “The radio itself is a direct sequence spread spectrum unit, using production radios for 2.4 GHz. The system may ultimately be deployed on an unlicensed basis in the 2.4 GHz band or elsewhere, but the high noise levels in that band in the test locations (commercial automobile race tracks) are unsuitable for development and testing of the product.”
“An Intersil baseband processor performs the Direct Sequence modulation and demodulation. It is part of a five-chipset developed for the 802.11b standard. It uses 1/4th of the standard 802.11 speed resulting in a narrow occupied RF bandwidth.”
The frequency band requested is allocated on a primary basis to the Amateur Radio Service, and coordination is to be performed with the ARRL. This application was granted on June 4.

Hyperion Technology Group filed an application (with supporting exhibit) for experimental license to support the development of a system capable of early detection of extreme weather phenomena, including wind shear, tornadoes and hurricane-spawned tornadoes. Operation is to be nationwide on 10.4-10.6 GHz. FCC staff questions this frequency selection, saying in correspondence to the applicant that there are two footnotes to the U.S Table of Allocations that are problematic. US58 prohibits pulsed emissions in 10-10.5 GHz. US59 prohibits any emission other than N0N in 10.5-10.55 GHz. Staff further observes that while experimental licenses are not always bound by allocation restrictions, there is great likelihood that NTIA would object to this application when it gets coordinated with government users. The applicant has suggested a compromise, and notes that the frequency range was selected based on the availability of relatively-inexpensive commercial off-the-shelf hardware for the initial research. Once the concept is validated and high-energy wind phenomena are better understood, it is the applicant’s intention to move to a different frequency and build custom hardware to support that frequency.

According to the Miller, this will be achieved by taking on-orbit state data to compare the degradation experienced by the DCFT to that of similar technologies such as Hall thrusters. In order to measure the thruster’s on-orbit performance, efficiency, and degradation, it is necessary to transmit sensor data and pictures obtained from an onboard camera to a ground station. Operation is to be in low-earth orbit (700-3000 km) on 2.4000-2.4835 GHz.
