12/3/2022 0 Comments Windows appstudio![]() ![]() NMEA messages contain lines of data called sentences. NMEA 0183 is the data specification standard that AppStudio uses to communicate with GPS receivers. WINDOWS APPSTUDIO MANUALMost high-accuracy GPS receivers support the NMEA sentences that AppStudio uses however, it's recommended that you check whether the receiver supports these NMEA sentences in the receiver's user manual before you try to connect it to AppStudio. WINDOWS APPSTUDIO FOR ANDROIDWhile Esri doesn't publish a list of supported GPS receivers for Android or Windows, a list of receivers used in testing on Android and Windows is provided. If you are using an iOS device, you must also use one of the GPS receivers supported on iOS. To improve the accuracy of positions, consider using a GPS receiver that supports differential corrections. To use a GPS receiver with AppStudio, the receiver must support the output of NMEA sentences. There are many GPS receivers available however, not all of them work directly with AppStudio. Choose a receiverĪppStudio can use the GPS that's built into a device, or you can add an external GPS receiver to obtain high-accuracy data. Typically, however, the more accurate a GPS receiver is, the more expensive it is and the more difficult it is to carry in the field. Numerous navigation satellite systems are available. The more frequencies the GPS receiver uses-and, consequently, the more signals it receives-the more accurate it is this is also true for GNSS: the more systems the receiver uses (and the more signals it receives), the more accurate it is. GPS satellite signals are transmitted on different frequencies. The accuracy of these receivers ranges from submeter to centimeter, depending on their ability to track and process satellite signals. ![]() Due to the widespread use of the term GPS to refer to both types of receivers, GPS is used as the generic term in this help.Ī high-accuracy GPS receiver precisely calculates geographic locations using information from GPS satellites. GNSS receivers can use various navigation satellite systems, while GPS receivers can only use the Global Positioning System (GPS) navigation satellite system. Global Navigation Satellite System (GNSS) is the standard generic term for navigation satellite systems. ![]()
