We are currently using the LC86GAAMD GNSS module in our project and would like to clarify whether this module supports Differential GPS (DGPS). Our goal is to reduce the 5–10 meter position jumps we observe in standard GPS mode and obtain more accurate and stable location data.
Could you please confirm:
Does the LC86GAAMD module support DGPS ?
If it does, what is the correct method to enable and use these features?
Are there any configuration commands or firmware requirements we should be aware of?
Any guidance or documentation you can provide would be greatly appreciated.
Module support SBAS (including WAAS, EGNOS, GAGAN, and MSAS) and
SLAS if under Qzss L1S signal in latest firmware…ask @Jasper for fw.
But be aware of previous 1.4 manual:
The LC86GAA states that it supports the RTCM protocol. Does this mean I can use DGPS? For example, if I have a base station using an RTK-capable module, but my mobile devices use LC86GAA modules that do not support RTK but do support RTCM, can I send data from the base station to the mobile devices to perform position correction?
What do you mean when you say that the RTCM input can be supported as DGPS? Could you please explain in more detail? I believe you have used the LC86GAA module before; what measures did you take to improve positioning and reduce jumps?
Thank you for the information. Currently, I have a mobile device with an LC86GAA module, and I want to improve positioning without changing it. I have the following scenario in mind: if I use an LC29HBA module that supports RTK+RTCM with a good external antenna as the base station, would it work with my mobile devices that have the LC86GAA module? The LC86GAA does not support RTK, it only supports the RTCM protocol.
I specific better:
for a base are sufficient that it only emits rtcm like LC86G or LC29HBS or AA, it does not need rtk engine but is enough only output RTCM MSM4 or 7 data.
Instead for the mobile device module,even if it is capable of treating rtcm, it is not sufficient for a better positioning solution, so a module that has an rtk engine like the LC29H DA BA CA EA series can obtain the differential correction by rtcm data in real time (aka RTK) from a base that outputs that (rtcm) data and transmit (the base) to the rover (the mobile device).
I have two devices, a base and a rover. I will use a better antenna on the base. I will receive RTCM output data from both the base and the rover, and I will perform RTK correction on this RTCM output data using software on Windows. Do you think this would work?
