The EM - 506 GPS receiver from USGlobalSat is built on the amazing SiRF StarIII chipset. Similar to the ET - 301 in technology, it comes with on - board voltage regulation, an LED status indicator, battery - backed RAM, and a built - in patch antenna. A 6 - pin interface cable is also included. Powered by SiRF Star IV, it offers excellent sensitivity and performance, even in tough urban and dense foliage areas. With SiRF CGEE technology, it can predict satellite positions for up to 3 days and start in under 15 seconds in most cases without network help. It features a 48 - channel receiver, extremely high sensitivity of - 163dBm, 2.5m positional accuracy, and fast start times (1s hot start, 35s/15s warm start, 35s/15s cold start with CGEE). It consumes 45 - 55mA at 4.5 - 6.5V. It measures 30mm x 30mm x 10.7mm and weighs 16g including the cable. You can also access its datasheet and product page.
Using the EM - 506 GPS receiver is quite easy. First, connect it to your device using the included 6 - pin interface cable. Once connected, turn it on and wait for it to acquire a satellite signal. It usually starts up quickly, especially with the SiRF CGEE technology. In most environments, it will start working within seconds. When using it, keep it in an area with a clear view of the sky as much as possible, especially in urban canyons or dense foliage areas. This will help it get a better signal and more accurate position. For maintenance, keep it dry and avoid exposing it to extreme temperatures. If you want to store it for a long time, make sure to remove the battery to prevent any potential damage.
