To do this configuration, it is necessary to open the GPS160. It is recommended that this operation is only carried out by an approved Digital Yacht Dealer/Distributor, any physical damage to the PCB will not be covered by warranty.   Before opening the GPS160, turn off all DC power to the unit and then remove the threaded mount by unscrewing the 3xM3 hex bolts using a suitable Allen Key. Then using a Torx T6 screwdriver, remove the three screws that hold the GPS enclosure together. Gently pull the enclosure apart being careful not to lose the O-Ring seals (1 large outer and 3 small screwRead More →

Some customers have been experiencing Russian GPS Jamming in Baltic countries, where the GPS doesn’t return to the correct location and it has to be fully rebooted. A way around this is would be to operate the units in GLONASS only mode and this is probably the easiest way to safeguard against GPS Jamming. The signals of the two types of satellites are very close together and it is extremely difficult to jam one frequency and keep the other frequency unaffected. GPS, the centre frequencies are 1575.42 MHz (L1), 1227.6 MHz (L2) and 1176.45 MHz (L5). GLONASS operates as frequency divisional multiple access (FDMA) andRead More →

This is pretty normal behaviour for a modern GNSS receiver and is a result of position “jitter” caused by multi-path signals and scintillation. Traditionally, older GPS systems used to apply a low pass filter (damping) to the calculated positions and this reduced the SOG and COG fluctuations when stationary. With the GPS160 and its highly accurate Tri-Data technology, we decided to not apply any damping so that the readings were as accurate and with as little lag as possible. The only down side of this approach is this 0.1 Knot indication when stationary, but as soon as you start moving you get the most accurateRead More →

The default GPS160 operating mode has been optimized to work well with the maximum number of installations. It is operating in “Tri-Nav” mode and will give the same level of accuracy as any of the other “Tri-Nav” modes. In “Tri-Nav” mode, satellites from all three constellations; GPS/GLONASS/GALILEO are used to work out the most accurate possible position. In over 90% of pleasure boat installations, the default mode is the best one to use and unless you know that your system can accept a faster update rate or can make use of the additional sentences, then we would not recommend that you change mode.
