Micro Modular Technologies Unveils MN5515HS GPS Receiver Module, Low Power and Fully Integrated GPS Receiver Module with Increased Signal Sensitivity

The MN5515HS GPS Receiver Module is a complete 20-channel receiver with improved cold-start acquisition sensitivity of -145dBm. Cold-start acquisition sensitivity specifies the lowest signal level at which the receiver can get a valid position fix, versus tracking sensitivity, which only means the receiver can track the satellites, but cannot determine a position fix. It measures only 15 x 15 x 2.9 mm, and features fast-acquisition hardware, integrated RF filtering, TCXO, reset circuit, and a real-time clock with on-board crystal. The user needs only provide DC power and a GPS signal; the MN5515HS will output the navigation solution in the widely-used NMEA 0183 protocol or in SiRF binary protocol. The 20-channel receiver allows all satellites in view to be tracked, providing an over-determined solution to minimize position jumps caused by individual satellite blockage. The fast-acquisition hardware design greatly reduces the time for signal acquisition when the receiver is initially powered up. The MN5515HS operates from a single battery supply between 3.0 and 3.6 VDC. For even further power reductions, the OEM design may use a power-saving mode via binary commands…

Micro Modular Technologies Introduces GPS Receiver Module with Increased Sensitivity

The MN5515HS is a fully integrated, low power GPS Receiver module in a
15 x 15 mm package

Micro Modular Technologies (MMT), a leader in small, power-efficient GPS modules unveiled the MN5515HS GPS receiver module, a low power, fully integrated GPS receiver module with increased signal sensitivity. The
new module is based on the SiRFstarIII GPS receiver chipset and offers increased coldstart acquisition sensitivity. “The increased acquisition sensitivity ensures operation in environments with extremely low level GPS signals,” said Larry Cleland, VP of Sales and Marketing for MMT. “Acquisition sensitivity is a much more important measure of realworld
performance of a GPS receiver than tracking sensitivity.”

The new module measures just 15 by 15 by 2.9 mm, and includes a Real-time Clock (RTC) circuit and crystal, internal RESET circuit, TCXO, and all RF and baseband processing. The MN5515HS requires only a single 3.3 volt power supply, and consumes less than 80mW in typical operation. This highly integrated module only needs DC power and a GPS signal and it will output the navigation solution in either NMEA-0183 or SiRF Binary protocol. The module operates over industrial temperature range of -40 to +85 degrees C, and is available in tube or tape and reel. It is lead-free, RoHS compliant.

The MN5515HS module is available now through MMT’s worldwide sales network. Also available now is an evaluation kit, the MN5515HS-EVK, which allows for easy connection of the GPS receiver module to a PC via USB interface and includes test software for realworld performance evaluation.
