Android & phonegap

I want to create android app using phoneGap & the problem with this is my app fetch current location, speed in backgroung like service. i heard that phoneGap also has the API called geolocation for calculating location & speed but they also mention that they doesn't gives us accurate one. I HAVE ANDROID CODE TO CALCULATE SPEED AND GET LOCATION BUT IN ANDROID . So my Question i created service & its contineously running in backgroung ? i want BEST way to get values given by service & stored into Sqlite phonegap database LOCALLY...? How should i do this...?

I short i have to use android service in phoneGap & use the values given by service also store the values WHERE both sqlite phonegap stores..?
