This app does all the calculations to reduce a sextant reading to a line of position on the map. All intermediate numbers are shown to check your manual calculations. • Perpetual nautical almanac • Calculation of the line of position (azimuth and distance) • Draws the line of position on the map. • Star Finder: just point your device to the sky to identify the navigational stars. • Save your readings, choose what to show on the map. A sextant is required to make full use of this app.}

This app is really good. Everything you need, full service. Not hard to learn. Wish list: option for latitude longitude and time in decimal seconds. Verbose position output and confidence value.

Hyper intuitive et simple. Une visée plus calcul en moins d’une minute. Toutes les droites sont mémorisées. On peut sélectionner celles que l’on va retenir en final. Le transport de droites se fait automatiquement. Il suffit de rentrer le cap et la vitesse (à partir du point arbitraire). Le rendu sur carte est super. Je l’utilise depuis des mois et ai comparé la précision par rapport à d’autres applis, y compris le calcul d’estime. Tout est exact. Un vrai jeu de descendre aussi une étoile, planète, ou la lune, le tout en ayant le téléphone dans sa poche. Le starfinder aide à confirmer l’emplacement des astres en mode automatique ou à l’heure et lieu que l’on souhaite. Le plus de cette appli : la rentrée des données sur une seule page, ce qui évite les erreurs. Un seul coup d’œil permet de confirmer les paramètres rentrés et déceler un éventuel oubli.

This app is terrific! It is good to learn the “long way” of plotting your position but once you learn, then this app makes it so much easier and faster. All you need is your sextant and your watch and let the fun begin.

You put your sextant reading and it will give you a line of position. No need for nautical almanacs. But it does show all the variable values so you can double check your own calcs.

The app is great but I can’t find where to read my fix after my observation of the lower limb of the sun

This app has everything that one needs to resolve several sights into a fix. Nothing is missing. There is no clutter of unnecessary “features”. The best app that I’ve seen for celestial navigation. The inputs are: * assumed position entered by user or taken from device's GPS chip * date and time entered by user or taken from device's GPS chip * celestial body selected by user from a list of sun, moon, planets and stars * altitude of the celestial body read from sextant entered by user (Hs) * index error, if any, entered by user The outputs are: * actual altitude of the celestial body (Ho) * calculated altitude of the celestial body body (Hc) * intercept distance and direction (towards/away) * azimuth (Zn) details of the calculation from sextant altitude to observed altitude are shown. details of calculation from assumed position longitude to LHA of body are shown. The calculated line of position can be saved to the "Records" and placed on the provided map via a single click. All calculated lines of position stored in the "Records" tab can be displayed or hidden from the map. This allows each set of sights to be viewed separately without having to delete the previous set of sights. A "Starfinder" uses the device's GPS and orientation to show each celestial body. NOTES: 1. By default, the stars are sorted by number...use "Options" -> "Settings" -> "Sort stars alphabetically" to sort by name rather than number. 2. By default, the time is set to local time rather than GMT/UTC.
