Abstract

The Unattended Ground Sensor (UGS) Community includes many programs slated to incorporate the JTRS Cluster 5 Transceiver into the baseline systems. However, due to a variety of technical challenges, it's unclear that the Cluster 5 Transceiver will be available in time to support requirements for near-term fieldings. As a result, program offices are beginning to investigate interim solutions for Software Defined Radios (SDR) capable of providing Cluster 5-like flexibility and performance. During the last 15 months, Nova Engineering has been developing the Core Transceiver, a unique multi-band, multi-rate, Software Defined Radio. The Core Transceiver operates in four bands (225-400 MHz, 560-698 MHz, 1350-1390 MHz, and 1755-1850 MHz) and is frequency-agile across these multiple bands, thereby providing maximum flexibility in frequency planning. The transceiver supports adaptable data rates from 100 kbps to more than 1 Mbps, enabling the device to satisfy requirements for sensor-to-sensor communications, as well as gateway links. This transceiver utilizes an Orthogonal Frequency Division Multiplex (OFDM) waveform for robust operation in ground-to-ground multipath environments. The Core Transceiver is compact in size (6.5" x 2.85" x 0.8") and designed for energy-constrained applications. This paper introduces the Core Transceiver requirements, design concept, and implementation, and outlines a strategy for applying this transceiver within the UGS Community.
