Hey @brocaar, can you also kindly tell how does the FPGA (present inside the v2 gateways) helps in encrypting the finetimestamps? and why can’t we encrypt the timestamps using v1 gateways?
we have setup 4 gateway for device location
we have installed geo-server and configured with collos subscription key
can you please help me for geolcation of device
we are using below gateway for geolocation
Hey @sagarpatel, are you using a v2 gateway, which consists of a FPGA, used for encrypting the fine timestamps?
we are not using v2 gateway, we are using below purchased gateway
Can you please guide us
@sagarpatel According to my understanding, for the geolocation to work, we need correct values of encrypted fine timestamps. These values can only be provided by v2 gateways. I suppose the gateway that you are using is a v1 gateway and it does not support FPGA. A v2 gateway has accurate geolocation capabilities as it has an integrated FPGA with it.
Please refer the following:
currently we have v1 gateway
any solutions regarding v1 gateway for geolocation?
Hey, @sagarpatel, we ourselves are looking to implement the following with the help of v1 gateways only, but no luck till now! Have you found anything on it yet?
we don’t find any solutions with v1 gateway
but we can directly call collos JSON Rest API with gateway parameter and get device location
Hi, @sagarpatel what is the accuracy of the resolved location you’re getting? Is it upto lora-geo-location standards?
Can you brief about the orientation of the gateways, how far they are located and the test scenarios your observed.
we are getting about 30 meters accuracy of resolved location based on lora-geolocation standard
For location resolving we have used 5 gateways please find below image of our gateway orientation
As per our test we are getting better accuracy in RSSI instead of RSSI with ToA
Thank you, @sagarpatel for your response! But what about resolving location only with TOA? Then, what’s the accuracy that you’re getting?
@pooja.mittal currently we are testing with ToA & RSSI for better accuracy.
@brocaar can you please guide us for better accuracy with ToA & RSSI algorithm
@sagarpatel, are you using ns precision timestamp? is it encrypted?
we are using plain GPS timestamp
@sagarpatel in nanoseconds or microseconds?
@pooja.mittal we are using nanoseconds
