abstract
New compact multiple channel/frequency OEM board GNSS receivers are being developed with the capability to meet some key critical hurdles for mass market utilization which include cost, size, and power. Control software that interface to these GNSS systems are typically built for PC or proprietary hardware systems which provide barriers of entry to many market segments. Mobile cellular phones are now powerful enough to interface to GNSS systems. GNSS receivers often come with an API that can be used to quickly build a mobile platform interface. The GNSS receiver can be controlled via Bluetooth by mobile devices for raw data collection and real-time solutions by passing DGPS or RTK corrections. GNSS controller software can be built on mobile cellular devices that can be shared on Windows Mobile, Android, or Apple platforms. Providing mobile controller software will reduce hurdles to mass market utilization by reducing cost and size of the controller application and hardware. This paper will discuss a software shareware 'App' product on a mobile cellular phone that can interface with a compact GNSS receiver. The process of augmenting the GNSS OEM receiver and the mobile cellular GPS receiver to quickly obtain RTK solutions will be presented. A demonstration of how the combination of the mobile cellular GPS, GNSS OEM receiver and the shareware software 'App' can be used for hydrographic, aerial platform, GIS, emergency response, and surveying/engineering applications is presented. The results discuss the methods used develop software for use in mapping and surveying applications.
