March 2009 Chapter 3 - MTP850 Ex/MTP810 Ex Product Information Manual 6866588D21-D
To assign a setting, put the pointer into the field value, click on the arrow, and drag the pointer to the
desired setting.
This field is an element in the codeplug structure for Unsolicited Report Profiles; the actual value
depends on the particular Profile.
GPS Unsolicited Uncertainty
This is the requested horizontal uncertainty to use for Unsolicited Location Reports. The value is a
measure for the accuracy of the location determination.
This field is an element in the codeplug structure for Unsolicited Report Profiles; the actual value
depends on the particular Profile. Type in the required value in meters.
If the requested uncertainty/accuracy is achieved from the GPS system, the report will be sent with
the requested uncertainty/accuracy. If the requested uncertainty/accuracy is not achieved, the
uncertainty/accuracy, which has been achieved is reported after expiration of the GPS Max
Acquisition Delay.
If an uncertainty value of 0 is defined, then no accuracy information is requested and the unsolicited
location report will not contain any accuracy information (shape type is point_2d or point_3d). If an
uncertainty value not equals to 0 is defined, then an accuracy information is provided within the
unsolicited location report (shape type is ellipse_2d or ellipse_3d).
GPS Maximum Data Age
Indicates the default maximum age (in seconds) allowed for data in Location Report message for
triggered reports.
Type in the required value.
GPS Maximum Acquisition Delay
Indicates the default maximum time (in seconds) allowed for the acquisition of the current location.
Type in the value. This value will be mapped to an actual value as shown in the second column of
the mapping table.
At the end of the specified acquisition period, the following will happen:
• If the terminal has a signal, the terminal will get the LRRP report with Location Data.
• If the terminal has not acquired a fix to the requested accuracy, the terminal will get the LRRP
report without location data and with an error indication plus the reason.
GPS Idle Report Period
This is the interval (in seconds) at which periodic Location Reports are sent outside Emergency
Mode (0 means never).
Type in the required value.
GPS Emergency Report Period
This is the interval at which periodic Location Reports are sent in Emergency Mode.
Type in the required value.
GPS Report Distance
Defines the distance interval at which distance-based Location Reports are sent.
Type in the required value.
Distance Check Interval
Maximum interval (in seconds) at which MS checks its position for position-based Location Reports.
