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.

  • Did a unplug-plug replacement for a 406A in a current application, same SparkFun GPS shield, same code, etc. Once I cycled the power switch on the shield, the 506 worked a treat.

  • Anyone flown this on a high altitude balloon yet, or have confirmation it works over 60K ft?

  • I see in the revisions that the 1PPS signal was changed to “directive”. Is the “directive” signal also timing quality, or is there a way get the 1pps back?

  • Is this not a 3.3v part like most GPS parts or am I reading the sheet wrong? Does that complicate it’s use with battery projects? Looks like a great part aside from that concern.

  • I am using the EM-406 with the GPS Arduino shield. Will this be a drop in replacement?

  • Hmm, Just in time for AVC…
