Ship Captain's Medical Guide 與 GPS Anti Spoof 使用情況與統計

Ever wonder what happens if you eye pops out of its socket? The answer to this and many other survival medicine tactics is included in The Ship Captain's Medical Guide. The Ship Captain’s Medical Guide app over 1,100 pages content developed by the United Kingdom’s Maritime and Coastguard Agency (MCA). The Ship Captain’s Medical Guide is intended for use on ships where no doctor is carried. The app includes recommended measures of prevention and treatment are therefore confined to those which can reasonably be expected of the ship’s officers. Now you can have access to this information too. Some topics covered include: - General principles of first aid - General assessment of the situation - Toxic hazards - General nursing - Care of the injured --- Internal injuries --- Head injuries --- Eye injuries --- Ear injuries --- Nose injuries --- Mouth and dental injuries --- Burns and scalds --- Dislocations --- Sprains and strains - Causes and prevention of diseases - Communicable diseases - Survivors - External assistance - Basic anatomy and physiology If you boat, hike, climb mountains, hunt, fish or spend time outdoors this guide provides you valuable information not found in traditional first aid and survival manuals.

GPS Anti Spoof

Instantly compare observed celestial navigation altitudes with high precision, live calculated altitudes. Shoot the Sun, tap pause in the app, and get instant feedback. Standard version includes data for the Sun, Venus, and two stars. The Pro version of the app is for serious navigation use and includes data for the Sun, Moon, Venus, Mars, Jupiter. Saturn. the 57 standard navigational stars, plus Polaris. Both versions function off-network and at sea however the standard version only works for three days off-network. The Pro version can function for weeks in the middle of the ocean without network access. This app calculates the exact altitude that should be observed in celestial navigation at sea or on land assuming that the GPS position is correct. No paperwork is required, no tables of corrections. All corrections are included automatically: index error, system time error, dip of the horizon, refraction, temperature and pressure corrections to refraction, altitude above sea level, parallax, and also gravitational deflection of the vertical (a correction of up 2 nautical miles not handled by any other celestial navigation sight-clearing product) are all included automatically. If the GPS position is wrong, due to Spoofing at sea, observations will not match. With this app and occasional quick sextant sights, mariners can reliably detect GPS spoofing. No GPS Spoofing? The app also functions as a celestial navigation trainer: take a sight and immediately compare against the app's display. No paperwork and instant feedback will improve celestial sextant skills in hours instead of days or weeks. The app works off-network, even in the middle of the ocean. If a network connection is available, the app will download temperature and pressure information automatically. Or weather data can be entered manually, if desired. The ephemeris data is generated from the same JPL numerical integrations of lunar and planetary motions used by the official Nautical Almanac and Astronomical Almanac. All coordinates are accurate to one second of arc, and displayed altitudes are accurate to a tenth of a minute of arc.
