Sailsafe. Anchor alarm. 2.0.4 APK
Sailsafe is an application designed toincrease safety in the anchoring of small and medium-sizedships.It lets you stablish a safety zone around your anchor and activatean alarm that will alert you in case your ship leaves that zone atany given time (very common situation when anchor drifting occursor the chain breaks). You will be able to see where the boat islocated on the map at any moment, which is very useful if it isdark or visibility is reduced.The safety zone can be set just indicating a radius.In PRO version, you can also specify an aditional exclusion zone todetect, for example, changes in wind direction that could put ourboat at risk if, for example, the coast is positioned itself toleeward.Sailsafe has been designed to maximize the safety after anchoring.Therefore, once the alarm is activated, not only the position ofthe ship is checked, but also the level of the battery in themobile device or the state of the GPS signal. If any of theseparameters fails, then the app will produce an audible alarm toinform about the specific problem. Thus, after setting the alarmyou can relax and trust Sailsafe. It will be watching foryou.Features:- It runs in the background.- Main screen shows useful information:1. Current position (latitude, longitude and accuracy of themeasure).2. Current security radius.3. Current drift.- Set graphically and easily a security zone with an optionalexclusion zone.- Wind forecast included (48h). You will be warned if the boat isexpected to be out of the security zone due to a wind change.- The ship and the security zone are always shown over a map withoptional satellite view.- Once the alarm is set, you can adjust the anchor position in caseit is not correct. Just indicate the actual bearing (read it fromthe compass) and estimated distance between the ship and the anchor(surface distance).- Option to ignore the current volume of the device and set it tothe max when the alarm is triggered.- Option to set a minimum battery level. When reached, the alarm istriggered.- Option to allow automatic alarm re-launch after a falsepositive.- Option to keep the screen on while the alarm is activated.- Option to call a phone number when the alarm is triggered.- Remote commands:1. An incoming call from a defined phone will reset thealarm.2. Send a SMS with the word STATUS to the on board device and itwill respond with another SMS containing useful information aboutthe location of the ship.- After a set number of seconds without GPS signal, the alarm istriggered.- Option to mute alarm tone after a set number of minutes (to avoidannoying pets in the boat if the alarm is triggered and nobody ison board).- Option to set the measurement unit (feet or meters).- Three modes of operation:1. Normal. GPS readings every 10 seconds. Simple algorithm todiscard odd positions. (Save battery when the device is notcharging).2. Fine. GPS readings every 2 seconds. Complex averaging algorithmbased on accuracy and time of the last 10 GPS readings to discardodd positions making the whole system smooth and robust. More powerconsumption.3. Continuous. GPS readings every 1 second. Same algorithm as infine mode. Optimus for adverse weather conditions. More powerconsumption.4. Poor GPS signal mode.- When re-enabling alarm, if ship moved less than 150 meters, youcan opt between keeping last anchor position (useful after a falsealarm) or using the actual GPS reading.
