Round develops micro GPS receiver

The antenna is already soldered onto the small circuit board, which is only 12 x 2mm, making wiring unnecessary.

The square, 10mm-wide and approximately 4mm-high antenna is positioned at a 90-degree angle from the circuit board.

This array lets the user watch the display as usual, for example, when using a GPS Smartphone, while the antenna points to the sky.

The actual reception module contains an antenna amplifier as well as filters for GSM bursts, in addition to the time-tested SiRF-III chipset with display of the coordinates in NMEA-0183-V3 protocol.

Harald Naumann, technical director at Round Solutions, says the Aarlogic GPS 3T is most suitable for the structure of small and efficient positioning systems, but also for custom-made Smartphones.

'The micro GPS receiver can be installed piggyback directly onto the circuit board of the device.

'It is switched on by simply using an on/off pin.

'In addition, the power consumption at a nominal 31mA is very small at a 3.3V supply voltage,' adds Naumann.

For the visualisation of the geo data received with Aarlogic components, a free test server is available on www.track4free.com.

Developers also receive access to a worldwide community for machine2machine communication, reachable on the company website.
