2.16 PSIMECEF ECEF sentence control command

PSIMECEF for enable/disable ECEF sentence output

Example: $PSIMECEF,W,1*64

Test Command

PSIMECEF,T

Example, send: $PSIMECEF,T*7A

Response:



$PSIMECEF,T,(0-1)*7B[0D][0A]

Parameters

See Write Command

Write Command

PSIMECEF,W,<mode>

Response


PSIMECEF,W,Ok


PSIMECEF,W,Error

Parameters

<mode> ECEF sentence mode

0: disable ECEF sentence output

1: enable ECEF sentence output

Example1, disable ECEF sentence output:

$PSIMECEF,W,0*65

Example2, enable ECEF sentence output:

$PSIMECEF,W,1*64

ECEF sentence:

When enable, will output ECEF sentence, for example:

$ECEFPOSVEL,072015.000,-2840662.813,4662059.129,328703

5.216,0000000.001,-0000000.002,0000000.003*2E

Which means:

$ECEFPOSVEL,<data_time>,<ECEF_pos_x>,<ECEF_pos_y>,<

ECEF_pos_z>,<ECEF_vel_x>,<ECEF_vel_y>,<ECEF_vel_z>*<c

hecksum>

ECEF_pos – are the vectors of coordinates in geocentric

coordinate system, format is XXXXXXX.YYY, unit is meter.

ECEF_vel – are the vectors of velocity in geocentric coordinate

system, format is XXXXXXX.YYY, unit is m/s.

Response

returns the ECEF sentence mode

IF read success:

PSIMECEF,R,Ok,<mode>

IF read error:

PSIMECEF,R,Error

Example:

Send: $PSIMECEF,R*7C

Reponse: $PSIMECEF,R,Ok,0*68

Read Command

PSIMECEF[,R]

Parameters

See Write Command

Note

1. The GNSS modules which support ECEF sentence control have this feature.



2.17 PSIMNMEA NMEA sentences output control command

PSIMNMEA for enable/disable NMEA sentences output and output frequency

Example: $PSIMNMEA,W,0,3,0,5,0,0,0*61

Example, send: $PSIMNMEA,T*78

Response:

$PSIMNMEA,T,(0-5),(0-5),(0-5),(0-5),(0-5),(0-5),(0-5)*7D

Test Command

PSIMNMEA,W,Ok


PSIMNMEA,W,Error

Parameters

<GLL> GLL sentence control:

0 - Disabled or not supported sentence

1 - Output once every one position fix

2 - Output once every two position fixes

3 - Output once every three position fixes

4 - Output once every four position fixes

5 - Output once every five position fixes

Reponse: $PSIMNMEA,R,Ok,0,3,0,5,0,0,0*6C

Read Command

PSIMNMEA[,R]

Parameters

See Write Command

Note

1. The GNSS modules which support NMEA sentence output control have this feature.
