# @ohos.geoLocationManager (Geolocation Manager)

The **geoLocationManager** module provides a wide array of location services, including GNSS positioning, network positioning, geocoding, reverse geocoding, and geofencing.

> **NOTE**
>
> The initial APIs of this module are supported since API version 9. Newly added APIs will be marked with a superscript to indicate their earliest API version.

## Applying for Permissions

Before using basic location capabilities, check whether your application has been granted the permission to access the device location information. If not, your application needs to obtain the permission from the user as described below.

The system provides the following location permissions:
- ohos.permission.LOCATION

- ohos.permission.APPROXIMATELY_LOCATION

- ohos.permission.LOCATION_IN_BACKGROUND

If your application needs to access the device location information, it must first apply for required permissions. Specifically speaking:

API versions earlier than 9: Apply for **ohos.permission.LOCATION**.

API version 9 and later: Apply for **ohos.permission.APPROXIMATELY_LOCATION**, or apply for **ohos.permission.APPROXIMATELY_LOCATION** and **ohos.permission.LOCATION**. Note that **ohos.permission.LOCATION** cannot be applied for separately.

| API Version| Location Permission| Permission Application Result| Location Accuracy|
| -------- | -------- | -------- | -------- |
| Earlier than 9| ohos.permission.LOCATION | Successful| Location accurate to meters.|
| 9 and later| ohos.permission.LOCATION | Failed| No location obtained.|
| 9 and later| ohos.permission.APPROXIMATELY_LOCATION | Successful| Location accurate to 5 kilometers.|
| 9 and later| ohos.permission.APPROXIMATELY_LOCATION and ohos.permission.LOCATION| Successful| Location accurate to meters.|

If your application needs to access the device location information when running in the background, it must be configured to be able to run in the background and be granted the **ohos.permission.LOCATION_IN_BACKGROUND** permission. In this way, the system continues to report device location information after your application moves to the background.

You can declare the required permission in your application's configuration file. For details, see [Access Control (Permission) Development](../../security/accesstoken-guidelines.md).

| ACCURACY | 0x201 | Location accuracy preferred.<br>This policy mainly uses the GNSS positioning technology. In an open area, the technology can achieve the meter-level location accuracy, depending on the hardware performance of the device. However, in a shielded environment, the location accuracy may significantly decrease.|
| LOW_POWER | 0x202 | Power efficiency preferred.<br>This policy mainly uses the base station positioning, WLAN positioning, and Bluetooth positioning technologies to obtain device location in both indoor and outdoor scenarios. The location accuracy depends on the distribution of surrounding base stations, visible WLANs, and Bluetooth devices and therefore may fluctuate greatly. This policy is recommended and can reduce power consumption when your application does not require high location accuracy or when base stations, visible WLANs, and Bluetooth devices are densely distributed.|
| FIRST_FIX | 0x203 | Fast location preferred. Use this option if you want to obtain a location as fast as possible.<br>This policy uses the GNSS positioning, base station positioning, WLAN positioning, and Bluetooth positioning technologies simultaneously to obtain the device location in both the indoor and outdoor scenarios. When all positioning technologies provide a location result, the system provides the most accurate location result for your application. It can lead to significant hardware resource consumption and power consumption.|

| -------- | -------- | -------- |
| UNSET | 0x300 | Scenario unspecified.<br>If this option is used, [LocationRequestScenario](#locationrequest scenario) is invalid.|
| NAVIGATION | 0x301 | Navigation scenario.<br>This option is applicable when your application needs to obtain the real-time location of a mobile device outdoors, such as navigation for driving or walking.<br>In this scenario, GNSS positioning is used to provide location services to ensure the optimal location accuracy of the system.<br>The location result is reported at a minimum interval of 1 second by default.|
| TRAJECTORY_TRACKING | 0x302 | Trajectory tracking scenario.<br>This option is applicable when your application needs to record user trajectories, for example, the track recording function of sports applications. In this scenario, the GNSS positioning technology is mainly used to ensure the location accuracy.<br>The location result is reported at a minimum interval of 1 second by default.|
| CAR_HAILING | 0x303 | Ride hailing scenario.<br>This option is applicable when your application needs to obtain the current location of a user who is hailing a taxi.<br>The location result is reported at a minimum interval of 1 second by default.|
| DAILY_LIFE_SERVICE | 0x304 | Daily life service scenario.<br>This option is applicable when your application only needs the approximate user location for recommendations and push notifications in scenarios such as when the user is browsing news, shopping online, and ordering food.<br>The location result is reported at a minimum interval of 1 second by default.|
| NO_POWER | 0x305 | Power efficiency scenario.<br>This option is applicable when your application does not proactively start the location service. When responding to another application requesting the same location service, the system marks a copy of the location result to your application. In this way, your application will not consume extra power for obtaining the user location.|
