Maximum output rate for NMEA messages

[meriemka]

I’m currently using a Reach RS3 connected via USB to PC, and I’m streaming NMEA messages (GGA and RMC) for real-time geotagging of images captured at 60 FPS.

In the ReachView configuration interface, I noticed that the maximum output rate for NMEA messages is limited to 10 Hz, and I understand this is due to internal GNSS solution update rate constraints.

My question is:
Is there any way to increase the effective positioning rate beyond 10 Hz
My goal is to minimize the georeferencing error between GNSS updates and 60 FPS image frames (~17 ms/frame)
Thanks

Probably not, especially after the max rate will be sacrificed ftom 10Hz to 5hz with a new update for new dual channel feature?

You may want to look at the new Ublox X20 or Mosaic X5? I would assume the next Emlid version would incorporate the X20 but who knows.

Reach Firmware 33 Beta 3 is out

Hi everyone! Meet the new Beta version of Reach firmware — 33 Beta 1. This release is available for Reach RS3, Reach RS2/RS2+, Reach RS+, and Reach M+ receivers (not available for Reach RX and Reach M2). Here is the list of the major changes. Added features: Ability to send corrections via 2 channels at the same time. Signal strength indicators in Reach Panel: for Reach RS2/RS2+ when receiving corrections over LoRa and for Reach RS3 when receiving corrections over LoRa and UHF. [Signal s…

Hi @meriemka,

Welcome to the Community!

@timd1971 is right. The maximum update rate is 10 Hz and cannot be increased. Would interpolating positions between GNSS updates work for your application?
