Detailed Description

template<std::size_t WordSize = 30>
class gnsstk::NavMsgDataWords< WordSize >

Define a class for storing NavFilterKey data in an array of 32-bit words. The template argument WordSize indicates how many of the 32-bit words contain data, e.g. 30 bits for GPS LNav and BeiDou D1 and D2 nav. WordSize cannot be larger than 32. This class is intended to be used as a template argument for NavFilterKey objects e.g. D1NavFilterData. It is not expected to be used directly by developers.

◆ dump()

template<std::size_t WordSize>

void gnsstk::NavMsgDataWords< WordSize >::dump	(	std::ostream &	s,
		unsigned	totalBits
	)		const

overridevirtual

Dump the contents of this message to the given stream.

Parameters

[in,out]	s	The stream to dump the data to.
[in]	totalBits	The total number of bits to dump (usually the number of bits in the subframe).

Implements gnsstk::NavMsgData.

◆ getBits()

template<std::size_t WordSize>

uint32_t gnsstk::NavMsgDataWords< WordSize >::getBits	(	unsigned	start,
		unsigned	num
	)		const

overridevirtual

Get a value, up to 32 bits, out of the nav message.

Parameters

[in]	start	The first bit (counting from 1 through the maximum number of bits in a single subframe) of the desired bits.
[in]	num	The number of consecutive bits to retrieve.

Returns: The value extracted from the nav message starting at start and ending at (start-1+num).

Implements gnsstk::NavMsgData.
