Kalman filter for loofs

okay..so you might not be a complete loof but I am..so I’m writing this post to the my future self..because he forgets a lot needs his memory to be refreshed every once in a while..go grab a pen paper. K.F- It is an iterative mathematical process that uses a set of equations and consecutive data … Continue reading Kalman filter for loofs


here’s how GPS works there’s a clock involved..the satellite sending out GPS signal has it..and satellite is orbiting the Earth about 20000 Km above surface with 14000 Km/Hr. So there’s a very precise clock on-board a very fast moving satellite..what da hell/..? Satellite sends a signal consisting of its orbital data and current timing. so … Continue reading break-a-leg/rtk

Kalman for half-witted

Kalman Filter, its a very versatile technique..ask about its usage..first used in navigation system of Apollo missions..used in Image processing and vision and stuff..and used in Robotics of course. Here’s why we need a filter to compute Orientation and explains complementary filter, which works okay. Complementary filters  are good and easy to understand..but they are static..i.e. gains … Continue reading Kalman for half-witted

ARM CORE M3 Basics

ARM..Advanced RISC Machine. I wasn’t really paying attention to the CMSIS and Startup files earlier…turns out they are quite knowledgeable. just a basic thing that I think one should know to avoid confusions- “Large and complex systems are designed by making small parts work independently and then integrate them together..so ADC’s I2C GPIO’s are not … Continue reading ARM CORE M3 Basics
