The 941X’s RECEIVER OPTIONS provide you with advanced control
capability over several of the unit’s GPS and DGPS navigation functions.
capability over several of the unit’s GPS and DGPS navigation functions.
When not using Differential GPS, you may notice that Speed-Over-
Ground readings obtained from the GPS satellite system are slightly er-
ratic, varying by up to several knots. The 941X’s SPEED AVERAGING
function can often improve the steadiness of these readings, at the ex-
pense of a slightly longer display reaction time when the speed changes.

The time over which your speed is averaged by the 941X may be selected
with this function, with values between two and ten seconds available.
Averaging may also be turned OFF completely for the quickest possible
reaction time.

A longer averaging time is useful at lower speeds, where the highest ac-
curacy is required, such as when you want to trawl at a certain optimum
speed. You will see a slower-changing, more steady display of your speed,
with a high degree of accuracy. Shorter averaging times, however, will
give you a quicker-changing display of your speed, but with less accu-
racy.
