MIA-M10Q - Integration manual
2.1.2.1 Dynamic platform
The dynamic platform model can be configured through the CFG-NAVSPG-DYNMODEL
configuration item. For the supported dynamic platform models and their details, see
Table 6 and
Table 7 .
Platform Description
Portable Applications with low acceleration, e.g. portable devices. Suitable for most situations.
Stationary Used in timing applications (antenna must be stationary) or other stationary applications.
Velocity restricted to 0 m/s. Zero dynamics assumed.
Pedestrian Applications with low acceleration and speed, e.g. how a pedestrian would move. Low
acceleration assumed.
Automotive Used for applications with equivalent dynamics to those of a passenger car. Low vertical
acceleration assumed.
At sea Recommended for applications at sea, with zero vertical velocity. Zero vertical velocity assumed.
Sea level assumed.
Airborne <1g Used for applications with a higher dynamic range and greater vertical acceleration than a
passenger car. No 2D position fixes supported.
Airborne <2g Recommended for typical airborne environments. No 2D position fixes supported.
Airborne <4g Only recommended for extremely dynamic environments. No 2D position fixes supported.
Wrist Only recommended for wrist-worn applications. Receiver will filter out arm motion.

Airborne <4g 80000 500 20000 Altitude Large
Wrist 9000 30 20 Altitude and velocity Medium
Table 7: Dynamic platform model details
Applying dynamic platform models designed for high acceleration systems (e.g. airborne <2g) can
result in a higher standard deviation in the reported position.
If a sanity check against a limit of the dynamic platform model fails, then the position solution
becomes invalid.
Table 7 shows the types of sanity checks which are applied for a particular dynamic
platform model.
2.1.2.2 Navigation input filters
The navigation input filters in the CFG-NAVSPG-* configuration group control how the navigation
engine handles the input data that comes from the satellite signal.
Configuration item Description
CFG-NAVSPG-FIXMODE By default, the receiver calculates a 3D position fix if possible but reverts to 2D
position if necessary (
auto 2D/3D ). The receiver can be forced to only calculate 2D
( 2D only ) or 3D ( 3D only ) positions.
