Starts a precise positioning tracking session for meter-level accuracy. Before calling this API, correction data source should be registered.

## Parameters

| Parameter | API type | Data type | Description |
| --- | --- | --- | --- |
| minIntervalMillis | Java | long | Minimum required time interval between position reports received from the location engine. Specified in milliseconds. |
| minIntervalMillis | Native | uint32 | Minimum required time interval between position reports received from the location engine. Specified in milliseconds. |
| cb | Java | ILocationReportCallback | Callback to report the location data ([ILocationReportCallback](https://docs.qualcomm.com/doc/80-PK177-134/topic/ilocation_report_callback_rtk.html)). |
| cb | Native | pp\_rtk\_LocationReportCallback | Callback to report the location data ([ILocationReportCallback](https://docs.qualcomm.com/doc/80-PK177-134/topic/ilocation_report_callback_rtk.html)). |
| ret | Native | pp\_rtk\_LocationStatus& | On success this is the actual return value from the API.<br><br><br>                <br>See [LocationStatus](https://docs.qualcomm.com/doc/80-PK177-134/topic/location_status_rtk.html). |
|  |  |  |  |

Note: 
        
- When `minIntervalMillis` is passed as 0, a callback is invoked as soon as the data is ready, i.e., engine minimum supported interval.
- Any other `minIntervalMillis` values currently default to 1 second internally and the precise positioning sessions operate at a 1 second interval.

## Returns

| Return | API type | Data type | Description |
| --- | --- | --- | --- |
| response | Java | LocationStatus | [LocationStatus](https://docs.qualcomm.com/doc/80-PK177-134/topic/location_status_rtk.html) |
| response | Native | qesdk\_transaction\_status | See [QESDK transaction status for Native APIs](https://docs.qualcomm.com/doc/80-PK177-134/topic/native_qesdk_class.html) for usage details. Use qesdk\_transaction\_status to confirm API call invocation. If successful, use the `ret` value for the actual API return value object. |
