Member Function Documentation

bool addIncompleteSF1Thru3 (  const long  sf1[8],
const long  sf2[8],
const long  sf3[8],
const long  sf1TransmitSOW,
const int  gpsWeek,
const short  PRN,
const short  track
) 
 

Store a subframe in this object.

This method is provided in order to provide a path to a EngEphemeris object for cases where a receiver only provides words 3-10 of subframes 1-3.

Note:
: It is important to appropriately determine the transmit time of the data. The parameters sf1TransmitSOW and gpsWeek should be consistent and should represent the time when the data in sf1, sf2, and sf3 were received. As a general rule, the transmit time should be somewhere in the range of 0-2 hours BEFORE the epoch time of the ephemeris.

: EngEphemeris objects built via this method will not contain valid TLM message data, A-S flags, and "Alert" bits. Methods getTLMMesage() and getASAlert() should not be used.

Parameters:
sf1 words 3-10 of navigation subframe1 stored in the 30 least-significant bits of each array index.
sf2 words 3-10 of navigation subframe 2
sf3 words 3-10 of navigation subframe 3
sf1TransmitSOW time (in GPS seconds of week) corresponding to leading edge of first bit of subframe 1
gpsWeek full GPS week number.
PRN PRN ID of source satellite.
track tracker number (typically receiver channel number).
Returns:
true if successful.

bool addSubframe (  const long  subframe[10],
const int  gpsWeek,
const short  PRN,
const short  track
)  throw ( gpstk::InvalidParameter )
 

Historically, EngEphemeris allowed calling programs to add data one subframe at a time.

Parameters:
subframe ten word navigation subframe stored in the 30 least-significant bits of each array index.
gpsWeek full GPS week number.
PRN PRN ID of source satellite.
track tracking number (typically receiver channel number).
Returns:
true if successful.
Exceptions:
InvalidParameter if subframe is valid but not subframe 1-3.

bool addSubframeNoParity (  const long  subframe[10],
const int  gpsWeek,
const short  PRN,
const short  track
)  throw ( gpstk::InvalidParameter )
 

Store a subframe in this object.

This method is provided in order to allow construction of an EngEphemeris object for cases where a receiver only provides the 24 msb of each word and strips the parity.l

Parameters:
subframe ten word navigation subframe (minus the six parity bits) stored in the 24 least-significant bits of each array index.
gpsWeek full GPS week number.
PRN PRN ID of source satellite.
track tracking number (typically receiver channel number).
Returns:
true if successful.
Exceptions:
InvalidParameter if subframe is valid but not subframe 1-3.

void setAccuracy (  const double &  acc  )  throw ( gpstk::InvalidParameter )
 

Set the value of the SV accuracy (in meters).

This is the only "set" method and is provided so that one can set the SV accuracy directly and thereby override the conversion of the SV accuracy flag to meters. This is usually used when entering data from some source other than an SV nav message.

Note:
Subsequent use of the addSubframe(), with subframe 1 info, or the setSF1() methods will overwrite any value set using this method.

This function converts the given accuracy to the appropriate SV accuracy flag and stores it in the accFlag data member.

Parameters:
acc the new value of SV accuracy in meters.
Exceptions:
InvalidParameter if the given accuracy value is invalid.
