Loctronix Corporation, a provider of unified positioning solutions for GNSS-challenged environments, has announced the availability of its new software-defined radio (SDR) module, the ASR-2300, for developing high-performance positioning, navigation and timing (PNT) and communication applications. The device is a multiple-input and multiple-output (MIMO) transceiver module incorporating two wideband Field Programmable RF (FPRF) transceivers (300 MHz to 3.8 GHz) from Lime Microsystems, 10-axis accelerometer/gyro/compass/barometer sensors, and a large programmable FPGA capable of over 300 MiB/sec sustained communications with a host processor via USB 3.0 interface.
The module’s nine integrated RF path options and low size, weight, and power characteristics contribute to ease of integration and portability. Accommodating both internal 1 PPM TCXO or external frequency reference, multiple ASR-2300s can be inter-connected via an expansion port and/or UART interface, supporting real-time reception / transmission of 4, 6, 8 or more signals without the need for significant additional hardware.
“The ASR-2300 delivers advanced SDR capabilities in a small, mobile form-factor enabling developers to readily create and field complex SDR-based solutions. The module moves SDR out of the lab and into production, providing the critical piece for tapping advanced, multi-sensor/signals of opportunity for high-performance PNT,” stated Michael Mathews, Loctronix’ CEO and Founder.
According to Mathews, “The ASR-2300 has multiple, fully-integrated RF paths supporting reception of GNSS, cellular, ISM band, and UHF signals of opportunity. The ASR-2300 will benefit SDR developers working on demanding scientific, military, aerospace and commercial/industrial applications.”With on-board flash for storing developer customisable firmware and FPGA logic, the ASR-2300 can be configured to operate in a variety of different power profiles, maximising battery life without requiring a host processor. The modules will be factory-programmed with only the RF receiver capabilities enabled. Developers can enable transmit functionality by modifying the firmware and waveforms.
To encourage innovation in PNT and communications applications, Loctronix has partnered with Lime Microsystems to provide the source materials for the ASR-2300 module under open source licensing at the Myriad RF project (www.myriadRF.org).
“The broad utility of the ASR-2300 makes it an ideal platform for prototyping and developing advanced applications in the communications and PNT markets. Developers can make their own boards using the documents and design database contained in the A2300 project and/or purchase hardware, development kits, support services, and licensed waveforms directly from Loctronix,” Mathews said.
“Encouraging collaboration between the open source community and industry is a natural way to promote innovation and accelerate growth of SDR technology. We are delighted to partner with Loctronix to make their innovative ASR-2300 SDR design available to open source developers for creating advanced SDR applications,” said Lime Microsystems CEO Ebrahim Bushehri, Ph.D.
The open source software package includes basic drivers for Linux and Windows environments enabling both GNU Radio and embedded C/C++ developers to interface with the ASR-2300 module. Developers can obtain source code and design documents for modifying the ASR-2300 to suit their own applications.
