Hi, I need the program used for implementtation of Differential GPS in arduino
how can i upgrade GPS localisation using equations of differential technique?
thank you in advance
#DGPS #GPS #LOCALISATION #PRECISION
The GPS module does the DGPS calculation, and the Arduino simply reads the result.

Interesting announcement on DGPS
https://www.navcen.uscg.gov/?pageName=dgpsMain
Also look at:
" * Position Accuracy: < 3 meters (all GPS technology has about 3m accuracy)
- DGPS/WAAS/EGNOS supported"
Position Accuracy Without aid:3.0m (50% CEP)
DGPS(SBAS(WAAS,EGNOS,MSAS)):2.5m (50% CEP)
Velocity Accuracy Without aid : 0.1m/s
DGPS(SBAS(WAAS,EGNOS,MSAS,GAGAN)):0.05m/s

If there was some cunning wheeze bit of software (only) to make the GPSs reported position more accurate, you would expect it to be widly used.
What level of position accuracy do you want, and where is the GPS to be used ?

I'm using the ublox neo 6M and i'm loiking for a accuracy <1m
we want to make a DGPS using a simple GPS ublox neo 6M in orther to have a an accuraacy < 1m

What new approach will you be using?
The Neo-6P does long term averaging. With other Neo-6 models, the best you can expect is about 3m accuracy, when outdoors with a clear view of the sky.
To get better than 1m accuracy most people use something like the Neo-8 or Neo-9 RTK system, with rover and base station.

This equipment claims "Models of GNSS receivers will let you scale all the way down to centimeter level to know exactly where a particular data point is located."

Trimble and WangGan seem to come up a lot with Land Survey GNSS equipment.
You wont get it.
And if it were possible, everyone would be doing it allready ..........
