Description: The EM-506 GPS receiver from USGlobalSat based on the spectacular SiRF StarIII chipset. This complete module is built upon the same technology as the ET-301, but includes on-board voltage regulation, LED status indicator, battery backed RAM, and a built-in patch antenna! 6-pin interface cable included.
This EM-506 GPS module is powered by SiRF Star IV, it can provide you with superior sensitivity and performance even in urban canyon and dense foliage environment. With SiRF CGEE (Client Generated Extended Ephemeris) technology, it predicts satellite positions for up to 3 days and delivers CGEE-start time of less than 15 seconds under most conditions, without any network assistance.

This thing has great accuracy. After the initial fix it could place my location on a map with pinpoint accuracy. The fix time is quick if you are under open sky. In a building it is a bit slower.

Ran this module up on my coffee table in the lounge, and despite being inside a double brick building, got a reliable fix remarkably quickly. NMEA data is pumping out as expected, and the provided interconnect cable had me connected up to my dev board really quickly.

Before I purchased, I inquired if it was suitable as a replacement for the redundant EM-406 and was told it was. However information about software changes like Baud rate will be required before it will work as a change over replacement so it was not a straight forward replacement as expected. We have not completed the software changes to make it work yet so I hope I am not premature providing this requested feed back. Relevant info at the time of inquiry before my purchase would have been appreciated as I had not booked my software writer to alter code.
Hi, Sorry about the baud mismatch. Other than that, this module has the same pin out (minus the 1pps which has been replaced with a Directive pin that outputs GPS states.) It has the same power parameters 4.5~6.5V. It is using the updated SiRF Star IV as compared to the 406’s SiRF Star III.
There is an example on page 14 of the datasheet that shows how to switch the settings of the device. The EM-406 was factory set to NEMA, with a baud of 4800. So your command will be $PSRF100,1,4800,8,1,0*0C
We have a number of these units working well in our equipment. Very accurate and easy to integrate.
