Re:有谁用OPEN APRS的没有？我的iphone，ipadmini使用的时候，发现无法后台运 ..
Q: Will iAPRS update my location automatically while I am moving?
A: NO. iAPRS is NOT meant to replace your mobile APRS transceiver. The intent is to provide a means of display (and location updating) for use when you reach a destination and wish to either post your location so other interested parties can see where you are, or for you to see who is nearby.
If iAPRS was used in a manner to duplicate the typical mobile APRS transceiver it would surely run the battery down in the iPhone, causing not only the iAPRS app to cease functioning in a relatively short period of time, but more importantly, it would cause the telephone functionality to no longer work sooner than you might like. The iPhone is, in reality, intended to be primarily a telephone.
This function will be available in a future release for those who don't worry about battery life.
Q: Can iAPRS post my location automatically on launch?
A: NO. You need to hit the 'LOCATE' button once iAPRS is ready in order to post your location.
The automatic posting on application startup was not included in order to give the user the ability to determine what location accuracy they wanted to send their location with. On initial startup the GPS takes a few seconds to lock onto the satellites, and this varies from location to location. If iAPRS posted it's location right away on startup it would often post a very poor location compared to the location that would be posted if there was a suitable delay for the GPS or cellphone triangulation to have it's time to work (and this time varies).
