gnsstk::LNavCookFilter Class Reference

Detailed Description

"Cook" GPS legacy nav messages by turning words upright. Data in LNavFilterData::sf are modified.

Attention

Processing depth = 1 epoch.

Examples

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

Member Function Documentation

cookSubframe()

void gnsstk::LNavCookFilter::cookSubframe ( LNavFilterData *  fd )

static

Turn an LNAV subframe data upright.

Definition at line 64 of file LNavCookFilter.cpp.

filterName()

virtual std::string gnsstk::LNavCookFilter::filterName ( ) const

inlinevirtualnoexcept

Return the filter name.

Implements gnsstk::NavFilter.

Definition at line 82 of file LNavCookFilter.hpp.

finalize()

virtual void gnsstk::LNavCookFilter::finalize ( NavMsgList &  msgBitsOut )

inlinevirtual

Filter stores no data, therefore this does nothing.

Implements gnsstk::NavFilter.

Definition at line 71 of file LNavCookFilter.hpp.

processingDepth()

virtual unsigned gnsstk::LNavCookFilter::processingDepth ( ) const

inlinevirtualnoexcept

No internal storage of subframe data so return 0.

Implements gnsstk::NavFilter.

Definition at line 75 of file LNavCookFilter.hpp.

validate()

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

virtual

Turn words in a GPS LNAV message upright. This results in the expected 0x8b preamble in the TLM and subsequent bits as expected per the IS-GPS-200.

Precondition

LNavFilterData::sf is set

Parameters

[in,out]	msgBitsIn	a list of LNavFilterData* objects containing GPS LNAV data.
[out]	msgBitsOut	the "cooked" subframes. All contents of msgBitsIn will be immediately seen in msgBitsOut.

Implements gnsstk::NavFilter.
