All docs are on the SD Cards ( Sd card, is not destroyed, if you put it inside the smartphone to read the PDF ) but you'll need a PC to setup the Wifi. Wifi is OK when light is red, gps is ok when light is Green ( blink is not good ). The Wifi lock to an existing AP ( AP2 or AP do not care ). You do not need external Power to setup "USB-C" make the job. you cannot connect to USB they remove "Echo" do not try you'll get crazy... philosophy is : "Wifi". not 5 stars because : Please Add the 1Euros MicroSD to SDCard !!! in some country this is very hard to find. please add a A4 Paper in the boxe "Picture of the system working", and the lines, i write above...

Dear Eric
1) You are right, we are really late with the documentation.. Preliminary version - https://eltehs.lv/ELT_RTKBase_v1.8.0_EN.pdf

2) The documentation will be available in a few days at https://gnss.store/blog/category/elt-rtk-base.html and the link to it will be in the product card.

3) Connecting to WiFI - wait for the "Internet" LED to blink and press the WPS button on the access point. Unfortunately, this was not in the old documentation.

4) The USB connector is the receiver connector. You can update the firmware through it using UPrecise.

5) Instead of an adapter, maybe a USB card reader would be better?

Hello, we are using the ELT0387 and had some questions regarding the 6pin connector.
1. Is the 5V line on the connector an input 5V or output?
2. What is the voltage level of the UART1 and UART2 on the connector?
3. What is the voltage level of the Timepulse?
4. When we measure the output of time pulse or the uart signal using an oscilloscope we can see digital signals but the Vmax is around 0.2-0.3v. Is there something wrong?


Shop owner reply (24/04/2025):
Hello dear
1. Input (Power suply for board)
2. 3.3V (TTL)
3. 3.3V (TTL)
4. Measure voltage! Probally you measure current. :-)

RTK GNSS DK with cm accuracy for surveying and mapping. Base kit.

Dear GNSS OEM contact team,
I am interested in purchasing the RTK GNSS Development Kit (ELT0130) with centimeter accuracy for surveying and mapping applications. Before proceeding with the purchase, I have a few questions regarding the product's specifications and usage details. Could you please provide detailed information on the following points?

1. Product Price: What is the current price of the RTK GNSS Development Kit (ELT0130) including all necessary components?
2. Position Accuracy: Can you confirm the exact position accuracy of the kit in RTK mode? What is the expected accuracy in standalone mode?
3. Base Station Range: What is the maximum effective range between the base station and the rover unit? How does the range vary under different environmental conditions?
4. Waterproof Capability: Is the equipment rated for waterproof performance? If so, what is the specific IP rating, and can the kit withstand marine or outdoor environmental conditions?
5. Data Formats: Which data formats does the RTK GNSS Development Kit support (e.g., NMEA, RTCM, UBX)? Are there any specific formats that are particularly recommended for use with Windows systems?
6. Presence of Attitude Sensors: Does the kit include an integrated IMU for attitude sensing? If not, are there options for integrating external IMU sensors?
7. RTK Subscription Fees: Are there any additional costs associated with using RTK corrections? If so, could you provide details on the subscription fees or any third-party services required?
8. Wireless Connectivity: Can the base station and the rover unit be connected wirelessly? What wireless technologies (e.g., Bluetooth, Wi-Fi, UHF) are supported for data transmission?

Thank you for your assistance. I look forward to your response.

Dear Konstantin, answering your questions
1. The price is listed at https://gnss.store/gnss-development-kits/147-81-elt0130.html
2. The accuracy is listed in the Ublox F9P receiver datasheet - https://content.u-blox.com/sites/default/files/documents/ZED-F9P-05B_DataSheet_UBXDOC-963802114-12824.pdf
3. Not standardized. As the range increases, the accuracy decreases (1 mm deterioration per 1 km of range) and the fixation time increases. Fixation at a distance of 500 km is possible, but the accuracy will be 50 centimeters, and the fixation time is hours.
4. Ingress protection IP67 - see https://gnss.store/gnss-development-kits/147-81-elt0130.html
IP67 is
6 = No ingress of dust; complete protection against contact (dust-tight)
7 = Ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1 meter (3 ft 3 in) of submersion).
5. Recording to the memory card is in GPX and UBX formats, corrections are in RTCM3 format, coordinates are sent to the mobile phone in NMEA. More details - https://www.eltehs.lv/manual/
6. NO. NO.
7. YES. You will probably need to pay for electricity and internet.
8. YES
9. When purchasing, you can select the Bluetooth module. Connection to WiFi and 4G/5G is done using a mobile phone.

Great quality and so far great performance.
I want to use https://www.geodesy.linz.govt.nz/positionzpp/ to post-process data. But that tool only accepts official antenna models. Is there an official antenna model that is basically equivalent to the ELT0123, that I can use as a proxy?
Thanks for your help!

Hi gnss store.
Couple of questions
- The survey antenna that is included, is it the LT0123?
- For a land survey job (perimeter of a mountain cabin land plot), where I need precision +- 5cm, is this kit an overkill or do you have an alternative set up to recommend?

Cheers, Idar


Shop owner reply (07/03/2025):
Dear, Idar
1) Yes
2) There is no other waterproof (IP67) equipment at the moment. Its appearance based on ELT0233 is planned in a month or two.

Very pleased with the basestation. Easy to setup. I am a novice in this.
I have a few questions however:
I have tried CSRS-PPP (data collection for 24 h.) and the build in PPP that converges. They seem to agree on longitude and lattitude however elevation differes a lot some 80 cm. Are they using different references? In my country we use DVR50 - I have a geoid .gtx file use to correct on my rover however here there is a consistent approx 20 cm difference when useing the CSRS-PPP for the basepoint, when compared to some know points I have from a professional surveyor. I have set pole height etc.
Any pointers?


Shop owner reply (04/03/2025):
Dear, Malthe
Read a good tutorial on frames - https://content.u-blox.com/sites/default/files/documents/reference-frames-correction-services-white-paper-online.pdf Read it, you will understand that "where" is closely related to "when". That is, coordinates measured 10-20 years ago need to be recalculated.

Built-in PPP from RTKLib, it uses AFAIK the ITRF frame. CSRS-PPP is at least PPP-AR, and maybe PPP-RTK, it is more accurate. About the methods - https://gnss.store/blog/post/rtk-ppp-and-autonomous.html

As for the height systems, they are different in each country. It makes sense to compare only the height above the ellipsoid, and not the height above the geoid.

What is the chipset of the USB serial interface please (e.g. FTDI, PL-2303)?
I'm wanting to validate that my DAQ platform will support this interface for NMEA / Correction data. Thanks.

Hi,
We are interested in getting additional information on NEO-M9V USB C GNSS UDR/ADR module with LIS3MDL magnetometer.
We do not understand how the LIS3MDL magnetometer is integrated with the NEO-M9V.


Shop owner reply (23/02/2025):
Dear, Andrew
"We do not understand how the LIS3MDL magnetometer is integrated with the NEO-M9V" - No way. The NEO-M9V outputs coordinates, the LIS3MDL outputs heading (the direction the drone is facing). Since the drone can fly sideways, the course angle (the direction of movement) output by the NEO-M9V is not related to the heading (the direction the drone is facing).

Hello,
I'm looking for a presentation of the M-cpie connections with the UM982. Where can I find this table?
Thank you
