Networking for assisted PNT

A networked radio from Thales is designed to meet soldiers’ need for assured positioning, navigation and timing (PNT) while on foot.

The MBITR2 is part of a broader defense effort to provide PNT solutions in case of GPS jamming or interference. The MBITR2 is one of a number of devices and technologies, many still in development, to address this need.

For instance, under a Small Business Innovation Research (SBIR) contract with the Air Force Research Laboratory, Navsys Corporation is testing a network-assisted PNT acquisition algorithm to run on tactical radios such as the MBITR2. The algorithm is designed to provide improved acquisition performance in a GPS jammed environment by leveraging an innovative assisted GPS (A-GPS) architecture where navigation and timing data are shared across the tactical radio network.

The AN/PRC-148B MBITR2 ground tactical handheld radio is small, light and power-efficient. It builds on the legacies of both the earlier narrowband AN/PRC-148 MBITR tactical handheld radio and the wideband AN/PRC-154 tactical handheld radio. It covers the 30–512 MHz frequency range.

When equipped with the MBITR2, dismounted warfighters can connect with the wideband tactical Internet protocol and the voice network via the Soldier Radio Waveform wideband channel, while maintaining contact via the legacy narrowband channel.

The MBITR2 is interoperable with MBITR radios already deployed. More than 200,000 are now in the field, and Thales said the earlier generation radios can be upgraded with a low-risk and cost-effective approach.

Further, the MBITR2 retains compatibility with the existing installed base of ancillaries.

MBITR2-WMBITR2 features

  • Two radios in one
  • Simultaneous two-channel (narrowband and wideband) operations
  • Adds a second wideband channel to the AN/PRC-148 to provide networking, data, and video capability
  • Retains the existing AN/PRC-148 JEM Type-1 capabilities and waveforms
  • Embedded GPS
  • Supports fielded ancillaries
