Hello to everyone. Firstly, I feel like I'm enjoying this new website more. Kudos for everyone who made it possible.
So, I have a Leica GX1230 (non-GG, GPS only) and the date is stuck on January 30, 2004. This is possible a frequently occuring issue as I have seen similar posts in the forum. I am trying to make it change it into September 2023 but I have not succeeded yet.
Receiver type: GX1230 (non-GG version, GPS only), SN455263, Art. 733245
Software End of Maintenance: 12.02.2015, FW v8.71, ME v2.127
What I have tried:
1- I have tried to thoroughly read the other topics on the forum regarding similar problems. The usual suggestion is to upload the latest firmware. Yet, this receiver is already running the latest version possible with v8.71. I cannot upload the newer v9.02 because this one demands a SW Maint. Date of 11.06.2015.
2- Concerning the Measurement Engine, Leica has published a document which says that all GX1230 receivers won't be able to compute a position or have an erroneous date after 9th December 2012. it says that to solve this issue, everyone should upgrade to the ME2 v2.127. Yet, my receiver already has this ME v2.217 version but still shows the erroneous date.
3- I tried to reset the onboard Almanac and let it under the sun for about 1 hour to force it to download a new one from the satellites. I also format he whole system RAM and rebooted the unit. After about 10 minutes, it could compute a new position but the newly-downloaded Almanac version is from February 2004 (02.02.2004).
4- Inside myWorld portal, there are several versions of the ME available (ME v2.217, ME v3., ME v4, and ME v6) I tried to upload the newer versions of the ME into the unit and it says "firmware successfully installed" but when I check the system information, it still shows ME v2.127. Apparently, the newer ME versions couldn't install despite returning a postive/successful message. Then, I tried to downgrade the onboard firmware from 8.71 to 8.50. This version of the firmware installed the ME v2.215 altogether. I formatted the system RAM, let it under the sun for another hour, but the downloaded Almanac version was again from 2004 and the onboard date is also from 2004. I reformatted the system and re-upgraded the system to firmware v8.71. This installed the ME v2.127 altogether and after this, I let the unit outside for another hour but the downloaded almanac was again from 2004. I tried to reset the Almanac several times but it won't budge. The downloaded Alamanc was always from 02.02.2004 and the onboard time is stuck on 31.01.2004
-------------------------------------------------------------------------------------------------------
What I have not tried:
1- Is there something I am completely missing? Has anyone faced and resolved a similar issue?
2- Inside the myWorld portal, there is also an "ALMANAC FILE" which is updated daily and is found under the Tools Tab. I don't know if this could be directly installed into the GX1230 unit instead of making it download an Almanac from the Sats and waiting several units. Unfortunately, I couldn't find any PDF document that describes the uploading instructions for this daily-updated "Almanac File". Is there anyone who knows how to use this daily-updated file and install it on the GX1230 receiver directly? I don't even know if this could be done for GX12300 units so any help on this is warmly welcome.
3- Concerning the Alamanc file from myWorld portale, it is a file with a "*.m00" extension. Yet, from the "Leica 1200 Technical Reference PDF manual" (at page 1326 to be exact), it says that the Almanac file is found inside the /DATA/GPS folder and should have an "*.sys" extension. I tried to hook up the CF card into my PC with a card reader but there is nothing inside this directory.
4- This might be a solution but I'm not even sure: Should I try to run it in RTK-mode as a Rover. I have a GX1230GG unit which has a correct date+time. Should I try to use the GX1230 unit as a Rover in RTK mode altogether wih the GX1230GG as a Base? That way, the correct date from the GX1230GG unit will be constantly transferred to the GX1230 and maybe will correct its onboard time? I'm not even sure about this but I feel that I need to ask.
I have some Leica GPS 300 systems, that I use for static observations that I upload to AUSPOS for processing (Australia's equivalent to OPUS), these have the static date rollover issue, however as I needed to clean the RINEX data prior to submitting (removing satellites with blank fields etc), I wrote some software that does this but also corrects the date in the observations file. The only thing it doesn't do is rename the file correctly.
