"@Nikola I've been talking to u-Blox about RTK for over a year. I didn't really want to mod my Drotek XXL M8T, but they conveniently have the serial TX/RX and power headerized so connecting it to a HM-TRP (3DR) type radio would be a breeze. And it's…"
"There are 2 that are currently under going in-orbit testing, and another 4 under going ground testing pending launch."
"From a south facing window sill I've had 3.01 pull in a maximum of 28 satellites across the GPS, GLONASS and GALILEO constellations using a generic mag mount antenna, and similar results with an external Garmin GA38, and in general upper 20's for a…"
"Ok, the Galileo signals share the same band as GPS, so if you have a GPS+GLONASS set up now, Galileo will be workable. You must enable Galileo via the CFG-GNSS command, and burn that in if you want it to stick. Also I believe there is a 3Hz…"
"@Melih, Sorry for animating this thread, but I stumbled upon it looking for something exactly like your HM-TRP on XBee board from the September 18, 2012 at 1:51pm post. Not sure if you still have any of those boards, or some related info. Thanks."
"@Nikola, Well the NEO-M8P has finally been announced publicly, offering GNSS RTK

"@Cala The 3.01 firmware works with the NEO-M8N and LEA/NEO-M8T. I've used it on several M8N modules, and on the NEO-M8T in the Drotek XXL. I've conversed and shared data with a couple of others who have M8T modules. You have to enable Galileo with…"
"The 3.01 firmware does not disable raw output, it changes the parameters and obfuscates things slightly.
The 2.01 (ROM/EXT) continues to function, so unless you have some compelling reason to use the unvalidated Galileo constellation you can flash…"

"Dean,
Only the M8T (2.30) firmware can generate RXM-RAWX, all M8 can generate TRK-MEAS.
The MAX-6Q should be able to generate RXM-RAW, but you have to do two things, a) send a firmware version specific command to enable them, and b) send a CFG-MSG…"

"ALL current uBlox offerings can output 'raw' measurements, the M8N via TRK-MEAS, only the M8T has the RXM-RAWX which is the officially blessed manner to get RINEX polished data."
"I've used these Duinopeak NEO-M8N GPS Shield for Arduino with Antenna mashed together with STM32 Nucleo and Discovery boards to record hourly RINEX observation files directly to a Micro SD card.
The TCXO's in the M8N series parts offer much better…"
