    hello
    i have 2 devices i need one of this devices follow the other one where it is going to stay close around 2 Meters
    and if its far away its send coordinates where it is throw GPS service

    Getting 2m resolution indoors with GPS is not likely, i.e. using 2 GPSs and subtracting the coordinates.

    If you just need to measure a distance of ~2m between two objects, use ultrasound. Measure time-of-flight. Make the slave a transponder, so that the distance between master and slave is derived from the time-of-flight in both directions (plus a fixed delay before the transponder replies).

    first thank you for your reply
    about first point i want to use GPS if the distance is too far for both of them to find each other but if they are in same range the slave have to follow the leader always

    if you could let me know if there is reference to build circuit do that

    I'm not convinced that you have thought this through or that you even understand the problem:rolleyes:.

    What is your background and experience in electronics? Based on the question, I am assuming it is low. In other words, you don't yet know how much you don't know. You are asking to do something that is very difficult.

    GPS receivers w/ antennas at 2M resolution
    GPS to microcontroller communication (
    Wireless communication between devices (undetermined amount of data, data communication protocol, communication rate, ...)
    Onboard calculations of x/y/z deltas
    Onboard calculations of x/y/z adjustments to position (distance, acceleration, deceleration, error, rate of change in error, ...)
    Power to all units
    Interference and datacomm quality / error handling

    Unless you are aware of all plug-and-play modules, then go for it. If you are building/programming yourself, then let us know where you stand with skill level so we can adjust our comments as needed.

    you are exactly correct
    i don't have experience in that field so that i was asking about it .
    may be I'm expert in other fields like computer hardware and networking 2.4 and 5.8Ghz and software development programing also and Android OS

    In terms of your design, what have you got so far?

    If you really don't know where to start and you have nothing then this is not for you because you are essentially asking how to do everything i.e. initial concept and specification, problem solving, mechanical hardware design, electronic hardware design, software design, hardware construction, prototyping, troubleshooting etc, etc......

    No in fact i can make it fly also i can control it very good i think i have good experience in that also i decide to add small computer running with Linux i can work perfect on Linux also so
    refer to my original post i dont know how to make slave follow the main this is my problem that i dont know about but capture and application on mobile phone or at computer is not hard for me as the follower slave

    thanks for help
    if the slave and man boards are already in market for sell please tell me also

    And how much time do you think you will spend developing this on your own.. WAY... more then $1k USD worth..

    Check out the airdog and its airleash
    https://www.airdog.com/

    I suspect multiple GPS units (one in quadcopter and one in wrist leash)/gyroscopes/magnetic compass,etc...

    Also soloshot camera..

    i understand your point exactly you should spend much money on model and demo
    but commercial should be cheaper and you get what you spent at long term

    i think i can make without computer for around 100$ and with computer around 300$ only and control with watch in hand works with android OS

    I'm trying any way
