GPS receivers using two or more antennae mounted separately and blending the data with an inertial motion unit (IMU) can now achieve ° in heading accuracy and have startup times in seconds rather than hours for gyrocompass systems. The devices accurately determine the positions (latitudes, longitudes and altitude) of the antennae on the Earth, from which the cardinal directions can be calculated. Manufactured primarily for maritime and aviation applications, they can also detect pitch and roll of ships. Small, portable GPS receivers with only a single antenna can also determine directions if they are being moved, even if only at walking pace. By accurately determining its position on the Earth at times a few seconds apart, the device can calculate its speed and the true bearing (relative to true north ) of its direction of motion. Frequently, it is preferable to measure the direction in which a vehicle is actually moving, rather than its heading, . the direction in which its nose is pointing. These directions may be different if there is a crosswind or tidal current.
Everything that I have learned this semester in my English class has helped me with my writing abilities. It has even helped me improve on my speaking and in conversations. One very important issue is the difference between “academic” writing and non-academic writing, formal and informal. I did know that formal writing has to be different from informal writing, but what Mr. Bennett taught me was how important the difference is. At the beginning of the semester I didn’t have muchconfidence in my writing abilities at all, but now I do. Thank you Mr. B.
