Geolocation

Im looking for a way to periodically send my geolocation to a web application i'm gonna host on a remote server. I've never implemented anything like this before but after researching online all morning this seems to me the simplest way to do it:

1) Purchase a suitable gps reciever
2) Set up an account with a third party GPS tracking service to which the reciever can push it's geolocation data
3) The web app would then pull the geolocation data via some REST api the tracking service provides

Is any of this technically feasible?
Is there a superior solution I should consider?
Could anyone point me in the direction of a gps tracking service that offers such an api? What about self-hosting the gps server using an open source solution?
