gnsstk::LNavParityFilter Class Reference

Detailed Description

Filter GPS legacy nav messages that fail parity checks. Nav message bits are assumed to be upright.

Attention

Processing depth = 1 epoch.

Examples

navfilterex-pseudo-container.cpp, and navfilterex-pseudo.cpp.

validate()

void gnsstk::LNavParityFilter::validate ( NavMsgList &  msgBitsIn, NavMsgList &  msgBitsOut  )

virtual

Check the parity of the nav subframes (per IS-GPS-200).

Precondition

LNavFilterData::sf is set

Parameters

[in,out]	msgBitsIn	A list of LNavFilterData* objects containing GPS legacy navigation messages (id 2).
[out]	msgBitsOut	The messages successfully passing the filter.
