Horizon GPS Data REST API This REST server enables workload access to static location or dynamic GPS receiver location and satellite data.

envutil -- utilities for getting configuration from environment variables.

gpsdc -- a Go client for the gpsd daemon Usage example: package main import ( "fmt" "gpsdc" ) func main() { var gps_monitor *gpsdc.Session var err error // Open socket to gpsd at specified address (using default here) if gps_monitor, err = gpsdc.Dial(gpsdc.DefaultAddress); err != nil { panic(fmt.Sprintf("Failed to connect to GPSD: ", err)) } // Add an inline Filter function gps_monitor.AddFilter("TPV", func (r interface{}) { report := r.(*gpsdc.TPVReport) fmt.Printf("TPV: Lat=%f, Lon=%f, Alt=%f\n", report.Lat, report.Lon, report.Alt) }) // Or a stand-alone Filter function skyfilter := func(r interface{}) { sky := r.(*gpsdc.SKYReport) fmt.Printf("SKY: %d satellites\n", len(sky.Satellites)) } gps_monitor.AddFilter("SKY", skyfilter) // Tell gpsdc to start watching (using the default watch command here) gps_monitor.SendCommand(gpsdc.DefaultWatchCommand) // Listen forever for reports (delivered to the Filters above) done := gps_monitor.Listen() <- done } This code is Based on the incomplete and apparently abandoned 2013 project: "https://github.com/stratoberry/go-gpsd" The majority of this code was copied directly from that project.

hgps -- a resource class for caching Horizon GPS data Cache your Horizon GPS data in a "smart" GpsCache instance.
