SENSOR_CATEGORY_LOCATION

SENSOR_TYPE_LOCATION_DEAD_RECKONING

Dead-reckoning sensors. These sensors first calculate the current location and then update the current location by using motion data.

SENSOR_TYPE_LOCATION_LOOKUP

Lookup sensors, such as those that provide information based on the user's IP address.

SENSOR_TYPE_LOCATION_STATIC

Fixed-location sensors, such as those that use preset, user-provided information.

SENSOR_DATA_TYPE_ADDRESS2

VT_LPWSTR

Street address, second line.

SENSOR_DATA_TYPE_ALTITUDE_ELLIPSOID_ERROR_METERS

VT_R8

Altitude error referenced to the World Geodetic System (WGS 84) reference ellipsoid, in meters.

SENSOR_DATA_TYPE_ALTITUDE_SEALEVEL_ERROR_METERS

VT_R8

Altitude error referenced to sea level, in meters.

SENSOR_DATA_TYPE_CITY

VT_LPWSTR

City.

SENSOR_DATA_TYPE_DGPS_DATA_AGE

VT_R8

Age of differential GPS data, in seconds.

SENSOR_DATA_TYPE_ERROR_RADIUS_METERS

VT_R8

Accuracy of latitude and longitude values, in meters.

A value of zero means that the accuracy level is not known. The Location API will give priority to sensors that provide a non-zero value for this field.

SENSOR_DATA_TYPE_FIX_TYPE

VT_I4

Fix type.

0 = no fix

1 = 2d fix

2 = 3d fix

SENSOR_DATA_TYPE_GPS_OPERATION_MODE

VT_I4

Operation mode.

0 = Manual. The GPS sensor is set to operate in 2-D or 3-D mode.

1 = Automatic. The GPS sensor can automatically switch between 2-D and 3-D modes.

SENSOR_DATA_TYPE_GPS_STATUS

VT_I4

Current data status.

1 = Data is valid.

2 = Data is not valid.

SENSOR_DATA_TYPE_LATITUDE_DEGREES

VT_R8

Degrees latitude. North is positive.

SENSOR_DATA_TYPE_MAGNETIC_HEADING_DEGREES

VT_R4

Heading, in relation to magnetic north, in degrees.

SENSOR_DATA_TYPE_NMEA_SENTENCE

VT_LPWSTR

The current NMEA sentence string.

SENSOR_DATA_TYPE_POSTALCODE

VT_LPWSTR

Postal code.

SENSOR_DATA_TYPE_SATELLITES_IN_VIEW_AZIMUTH

VT_VECTOR|VT_UI1

Counted array that contains azimuth of each satellite in view.

Data for vector types is always serialized as VT_UI1 (an array of unsigned, one-byte characters). This data field must contain each value as an IEEE eight-byte real value (VT_

R8). Use -1 as a placeholder for empty values.

SENSOR_DATA_TYPE_SATELLITES_IN_VIEW_ID

VT_VECTOR|VT_UI1

Counted array that contains the ID of each satellite in view.

Data for vector types is always serialized as VT_UI1 (an array of unsigned, one-byte characters). This data field must contain each value as a four-byte unsigned integer (VT_UI4).

SENSOR_DATA_TYPE_SATELLITES_IN_VIEW_STN_RATIO

VT_VECTOR|VT_UI1

Counted array that contains signal-to-noise ratio for satellites in view.

Data for vector types is always serialized as VT_UI1 (an array of unsigned, one-byte characters). This data field must contain each value as an IEEE eight-byte real value (VT_R8). Use zero as a placeholder for empty values.

SENSOR_DATA_TYPE_SATELLITES_USED_PRNS

VT_VECTOR|VT_UI1

Pseudorandom noise codes for satellites that are used in a solution.

Data for vector types is always serialized as VT_UI1 (an array of unsigned, one-byte characters). This data field must contain each value as a four-byte unsigned integer (VT_UI4). Use zero as a placeholder for empty values.

SENSOR_DATA_TYPE_STATE_PROVINCE

VT_LPWSTR

State/province.

SENSOR_DATA_TYPE_VERTICAL_DILUTION_OF_PRECISION

VT_R4

Vertical dilution of precision.
