Track parameters setting
Command format
Turning V,A,D,S,dS
Parameters
V
– minimum speed that enables detailed turn by turn track, [km/h];
A
– minimum turn angle for device to record track point, [º];
D
– when this distance is exceeded another packet is saved to device memory,
[m];
S
– when this speed is exceeded for dS-multiple amount another track point is
recorded, [km/h];
dS
– speed exceeding step, [km/h].
Explanation
Configures track detail representation.
Example
Request: Turning 3,10,300,60,20
Reply: TURNING:Speed=3,Angle=10,Distance=300,SpeedEx=60,SpeedDelta=20;
Command format
WrPeriod x,y
Parameters
x
– packet memory record time in motion, [sec.];
y
– packet memory record time when the vehicle stops, [sec.].
Explanation
Packet memory record time when the vehicle is moving or when it stops.
Example
Request: WrPeriod 60,180
Reply: WRPERIOD move=60 parking=180
Command format
GPS.Correct OnOff,MaxWrong,MaxHDOP,Spd,Acc,Jump,TravelSpeed
Parameters
OnOff
– GPS data filter on(1) or off(0);
MaxWrong
– the number of wrong coordinates to be filtered (the recommended
number is 5). This parameter accounts errors of acceleration exceed and jump,
for other parameters coordinates are always filtered;
HDOP
– Maximum HDOP. When it is exceeded coordinates are not updated;
Spd
– Maximum speed. When it is exceeded coordinates are considered false and
are not updated, [km/h];
Acc
–GPS or GLONASS data based acceleration;
Jump
– Maximum coordinate jump in the nearest 2 seconds, [m];
TravelSpeed
– Minimum speed for coordinates to be updated, [km/h]. This
function is not suitable for low speed vehicles (tractors, asphalt placing machines)
Explanation
Allows filtering false coordinates: when the vehicle stops, is in or out of tunnels,
near high-rise buildings
Example
Request: GPS.CORRECT 1,5,2,150,3,50,3
Reply: GPS.correct: OnOff=1, MaxWrong=5, MaxHDOP=2, MaxSpd=150,
MaxAcc=3, MaxJump=50, MaxTravelSpeed=3;
Command format
GPS.Correct2 MaxNoSatTime,MinSatStart,MinSatWork
Parameters
MaxNoSatTime
– maximum time without satellite connection when no
disconnection is registered, [sec.];
MinSatStart
– minimum satellite number to be connected to when the device is
on;
MinSatWork
– minimum satellite number in operation mode. If the number is
smaller a disconnection will be registered.
Explanation
These settings affect coordinates updating, if filtering is on by
GPS.Correct
command.
Example
Request: GPS.CORRECT2 10,5,4
Reply: GPS.correct2:MaxNoSatTime=10,MinSatStart=4,MinSatWork=3;
