MC60 GPS no Latitude, Longitude data

Hi, I have been trying to get GPS data from MC60 module by sending AT command from a controller. I am not able to get GPS coordinate after sending AT+QGNSSRD?. I am double checked that the antenna(patch antenna) is connected. Herewith i have provided the log information.

Dear Logaesh,
As per the log, the module didn’t observe one satellite. Obviously the module didn’t receive GNSS signal. Please confirm the following conditions:
1, Put your patch antenna outdoor with open sky.
2, Respectively confirm that the patch antenna and MC60 are both normal.
3, Please refer to “Quectel_MC60_Hardware_Design_V2.1” to double check.

If possible, could you share your antenna design with us for review?

Hi sir,
Thank you for your concern. I have been contacted by your local FAE in bangalore, India. He has been reviewing our design. Moreover the issue is in our PCB design and we are currently working on it. So i likely to close this ticket.

Thank you once again for your support.

hello Logaesh.
excuse me, I have this problem(no Latitude, Longitude data).
Are you solve this problem?

if you solve this problem, could you please say me how you solved the problem?
thank you.

Hi sir
Does the module have NMEA sentence output? Could you provide us with a print log?

Is the antenna design active or passive? Could you provide us with part of the GNSS design for review, and also ensure that the GNSS antenna is placed in the open sky.

Hi Albert…

I am very grateful. The problem is almost solved. But using 13.56MHZ RFID antenna !!!

That is, the antenna is passive.

And considering the active and passive ceramic antennas that I used, this antenna (RFID antenna) has answered almost better than the passive and active ceramic antennas !!

Of course, maybe they were defective!

By disconnecting and connecting the module power supply, It takes about 2 to 10 minutes for the module to find and locate. Of course under the roof of the room located on the roof.
But when he finds it, it is very careful.

This antenna has very good accuracy in one place, such as rooms that are placed on the roof.

Is it possible that we can somehow locate on the ground floor of the house or even the basement?

Is it possible to reduce the waiting time for the location?

this is a part of log file, while the module can’t find locate. :point_down:

Thank you.

Hi Sir
1.Do you mean FPC antenna by RFID antenna?Since satellites are circularly polarized , generally circularly polarized antennas are better, such as ceramic antennas. But the specific performance depends on the debugging of the whole machine.

2.The GNSS signal is relatively weak under the roof of the room, and it takes longer to locate. There is no satellite signal in the basement, so it is impossible to locate.

If it is a vehicle product application, we have an inertial navigation module, which can also be located in the basement.

3.Please refer to the EPO function in “Quectel_MC60_Series_GNSS_AT_Commands_Manual_V1.3.pdf”. Using this function, the satellite ephemeris data can be downloaded to the GNSS module through the network, which can speed up positioning.

Hi Albert. Thank you so much.
this is my Antenna.it is a 13.56MHZ Coil Rfid Antenna.

Could you explain more about this? :point_up_2: :point_up_2:
ِDoes Quectel Company has a source or reference about this?

Excuse me. Thank you.

Hi Sir
We have inertial navigation modules for in-vehicle products, please refer to the attachment.

Best Regards

is the Location of this module Better Than the Location of the MC60 module?

Hi Sir
The difference between MC60 and L26DR is that when there is no GNSS signal, L26DR can output location information, but MC60 can‘t. However, L26DR module is suitable for vehicle-mounted products, not suitable for other portable products, etc. This is determined by an algorithm.
