u-blox 1.8-Volt GPS Module

u-blox has released a new low-voltage GPS module — the NEO 5D. Operating at 1.8 volts, the module require 40 percent or more less power compared to its predecessors in the 50-channel u-blox 5 engine product line: 72 mw @ 1.8V in the “Eco” mode and 77 mW @ 1.8V in the “maximum performance” mode. The module comes in a 12x16x2.4-millimeter package and employs u-blox’s SuperSense acquisition and tracking technology with a reported reacquisition and tracking sensitivity down to –160 dBm. Cold-start acquisition sensitivity is -143 dBm with a time to first fix of 32 seconds.

GPS/GLONASS Reference Clock

Pendulum Instruments, an Orolia Group company, offers the GPS-12RG, a combined GPS and GLONASS controlled frequency standard. This portable (weight, 3.1 kilograms) reference clock is designed for laboratory and telecommunications applications and can trace its operation to both GPS and GLONASS satellites. An internal rubidium oscillator provides stability of a few parts in 10-12, also in hold-over operation in cases when satellite contact is lost, according to the company.

OEM GPS Receiver with Integrated Antenna

The UC322 from Fastrax combines SiRF’s 20-channel GSC3LT single-chip GPS receiver with an on-board chip antenna in a package measuring 10.4x30x2.9 millimeters. According to the company, the UC322 has a tracking sensitivity of -159 dBm and power consumption of 90 mW and 3.3 volts. The antenna does not need a separate ground plane. Instead it utilizes the unit’s own printed circuit board (PCB) for gaining the best antenna signal. A new companion product, the IT321, is available without the integrated antennas.
