Use AnchorSentinel to provide navigation services and protect your boat.
AnchorSentinel is a nautical program with three primary purposes: It provides an accurate position, speed and bearing (true and magnetic) while underway, it stands sentinel against anchor drag while at anchor, and it provides an arrival alarm for a specified travel distance. AnchorSentinel relies on the fact that most Android devices have a built-in GPS receiver able to determine its position within a few meters, adequate accuracy for AnchorSentinel's purpose.For boaters who haven't been in dangerous situations, or who don't anchor very much, I should say that an anchor watch is a very good idea, and an Android device is an ideal platform for this task because it requires very little power, it operates independently of the boat's primary navigation and power systems, and it provides a secondary source of accurate position information in an emergency.
TankCalcAndroid analyzes storage tanks -- incremental volumes, weight, and more.
TankCalcAndroid is an Android-based version of my well-known storage tank analysis program TankCalc. I created it on hearing from a number of tank farm managers who wanted a more convenient way to analyze storage tanks in the field. This version includes most of the features of the desktop version — the table generator, the 3D viewer, even the anaglyphic true-3D viewing mode. It also has the ability to email its results to a user-provided address.Best of all, TankCalcAndroid is available at the same reasonable price as the original — it's free. There are no gimmicks or strings attached, and unlike so many Android applications, there are no ads.For those in government and safety-critical positions, TankCalcAndroid's source code is available for inspection and validation, and its mathematical methods are fully described at the TankCalc home page.The TankCalcAndroid Home Page is located at http://arachnoid.com/android/TankCalcAndroid
SatFinderAndroid is a geostationary satellite location and dish alignment tool.
Let me say up front that SatFinderAndroid is free, there are no ads, and there are no "pro version" appeals or come-ons. This program is exactly what it appears to bea free, useful tool for locating and pointing satellite dishes.SatFinderAndroid is an advanced Android-based geostationary satellite location and dish alignment tool. It includes a database of all geostationary satellites worldwide, and it provides detailed pointing instructions for all of them. It also has a list of popular satellite receiving dish models with pointing data for them as well. And more, it has a way to superimpose the locations of your selected satellites directly on a live camera picture of the sky at your location. The picture on this page shows a typical display of four user-selected satellites, positioned on the sky in their correct locations. SatFinderAndroid also has another pointing method, meant for Android devices without cameras, that uses your Android device as an azimuth and elevation sighting tool.SatFinderAndroid takes what was once a rather complex technical job requiring a knowledge of ZIP codes, city and state names, or geographic..
TidePredictor is a powerful tide/current prediction resource.
TidePredictor is an efficient and complete tide/current data resource. It contains a worldwide database of more than 3300 tidal reporting stations. It display a daily tide/current prediction graph and an adjacent calendar for the month.TidePredictor doesn't need an Internet connection to function, which makes this application ideal for boaters and others who need tidal information in remote locations.TidePredictor can export its predictions in the form of a graphic file (for the detailed daily graph) and an HTML page (for the monthly calendar).Oh, one more thing. TidePredictor is freethere are no ads, there's no upgrade to a pro version, no annoying come-ons. Free. Did I mention that it's free?TidePredictor is the thirdand by far the besttidal forecast program I've written over a period of fifteen years. In more than 90% of cases, its predictions are identical to those printed in tide tables. This is a program written by someone who understands the physics, the math as well as the needs of sailors (I've sailed solo around the world).I've performed some exhaustive tests, but if any difficulties arise in this new application,..

CarpeTempus is a complete, powerful Android alarm/timer application.CarpeTempus will accept any number of alarms (particular time of day, and day of week, month, year, etc.) or timers (durations in seconds. minutes. hours, etc.).When it's time for CarpeTempus to alert you, it will speak the message you choose, or play an alarm ringtone, or play a piece of music you choose.The CarpeTempus alarm scheduler is very sophisticated — you can choose a time of day, one or more days of the week, one or more days of the month, or a particular day of the year — or any combination of these.CarpeTempus timers are much like alarms, except they're meant for time durations, not times of day. You can set time durations from one second to 100 hours. When the time arrives, all the features of the alarm scheduler are available — spoken messages, ringtones or user-selected music.Once you have programmed some alarms and timers, you can put your Android device in standby mode. Then, when it's time for an alarm, the CarpeTempus service daemon will wake up, turn on the..
