NEO-F10N - Integration manual
Platform
Description
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.

Table 8: 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 the limit of the dynamic platform model fails, the position solution becomes
invalid.
shows the types of sanity checks which are applied for a particular dynamic platform
model.
2.2.2 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 it reverts to 2D
position if necessary (auto 2D/3D). The receiver can be configured to only calculate
2D (2D only) or 3D (3D only) positions.
CFG-NAVSPG-CONSTR_ALT, CFG-
NAVSPG-CONSTR_ALTVAR
The fixed altitude is used if fixMode is set to 2D only. A variance greater than zero
must also be supplied.
CFG-NAVSPG-INFIL_MINELEV
Minimum elevation of a satellite above the horizon to be used in the navigation
solution. Low-elevation satellites may provide degraded accuracy, due to the long
signal path through the atmosphere.
CFG-NAVSPG-INFIL_MINSVS, CFG-
NAVSPG-INFIL_MAXSVS
Minimum and maximum number of satellites to use in the navigation solution.
There is an absolute maximum limit of 32 satellites that can be used for navigation.
