How to transform given latitude and longitude data to map frame
I am working with a multi sensor RTK-GNSS for localization of my robot. This is the data I am getting from the GNSS system. How to relate this data to my robot map frame for navigation?
Convert ECEF Velocity to NED Velocity
My GNSS modules gives me one NMEA packet with ECEF velocity. My doubt is about how i convert these 3 vectors to NED frame. Can i use the conventional matrix rotation MathWorksRef. If yes, i use the ...
GNSS Dead Reckoning -- Sensor Fusion Filter not necessary?
My question might be a bit off-topic but I don't know where else to ask. When I do have a GNSS Module with integrated IMU and <...
Sensor fusion of GNSS and IMU using UKF
I do have a land-based robot with an IMU and a GNSS receiver. From the IMU, I get the velocity and acceleration in both $x$ and $y$ directions. From the GNSS receiver, I get the latitude and ...
Confused about time systems in ephemeris computation (from GPS subframes)
I am using the gnss-sdr library to compute ephemeris from the GPS message, and to try to make sense of things, I am reading the well-known IS-GPS-200E specification. To compute ephemeris, the time ...
All-in-one GNSS localization solution (hardware+software) [closed]
Is there something like an all-in-one satellite based localization solution that would contain both hardware and software to do GNSS localization for robotics? I mean a package that would also contain ...
