View detailed test resultsZephr Positioning in Action
The Zephr Positioning SDK delivers centimeter-level accuracy and real-time orientation in real applications and environments.
Precision Orientation
Precise heading knows exactly where you are looking, aligning virtual content with the real world.
High Positional Accuracy
Measured 2X improvement in accuracy over traditional GNSS in both obstructed and open-sky environments.
6DoF Orientation Tracking
Real-time complete 6DoF orientation including sub-meter spatial positioning for dynamic environments.
Perfect Integration with Zephr Local AI Platform
The Zephr Positioning SDK is designed to work seamlessly with the Zephr Local AI Platform. Use the SDK to obtain precise position and orientation data, then leverage the Enhanced Places API or Zephr MCP to enrich that data with contextual place information.
Real-time Position Data
Get precise lat/lng coordinates and orientation information
Contextual Place Data
Enrich position with nearby places and points of interest
Seamless Workflow
Single authentication system and consistent APIs
Integration Example
// Initialize Zephr SDK and request location updates
ZephrLocationManager.start(this)
ZephrLocationManager.requestLocationUpdates(object : ZephrEventListener {
override fun onZephrGnssReceived(event: ZephrGnssEvent) {
val location = event.location
if (location != null) {
// Use position with Zephr Enhanced Places API
val places = zephrAPI.searchPlaces(
lat = location.latitude,
lng = location.longitude,
distance = 10
)
}
}
override fun onPoseChanged(event: ZephrPoseEvent) {
// Handle orientation updates
val yaw = event.yprWithTimestamp?.first?.get(0)
val pitch = event.yprWithTimestamp?.first?.get(1)
val roll = event.yprWithTimestamp?.first?.get(2)
}
