Ready to Navigate!

After three decades of increasingly widespread use, satellite navigation-based services have changed significantly, especially for general users in the mass market. New technology enablers such as assisted GPS (A-GPS), the use of massively parallel correlation, and the application of advanced positioning techniques have significantly enhanced the time-to-first-fix (TTFF) and sensitivity of today’s receivers.

GPS has been widely used as a navigation sensor for numerous applications including unmanned aerial vehicles (UAVs). Many researchers have devoted considerable efforts to expand the role of GPS in guidance, navigation and control to determining an aircraft’s attitude. That would enable us to use a GPS receiver as a sensor for an automatic control system as well as a navigation sensor.

Wide-Area RTK

A common assumption in real-time kinematic (RTK) techniques is that the differential ionospheric delay between a GNSS transmitter and each of the roving or reference receivers is negligible. However, increased position uncertainty — spatial decorrelation — is usually allocated to the baseline receivers as baseline distances increase.

A refinement of this assumption comes with the network RTK (NRTK) using a set of permanent receivers to mitigate atmospheric dependent effects, such as the ionospheric delay, over distance.

Taking Positioning Indoors

Wireless local area networks (WLANs), popularly known as Wi-Fi, were originally designed for data applications. Over the past decade or so, WLAN infrastructure has been implemented for high-speed wireless Internet access in homes, “hot-spots,” university campuses, and corporate buildings. Hundreds of millions of Wi-Fi access points (APs) are deployed in major urban areas worldwide.

First GPS Block IIF Satellite Moves to Cape Canaveral: Launch Window Opens Mid-May

First Block IIF Satellite (Boeing)

[updated Februaary 16] The first Block IIF satellite is undergoing final launch preparations after arriving at Cape Canaveral Air Force Station in Florida aboard a Boeing-built C-17 Globemaster III airlifter.

Space Vehicle 1 (SV-1), the first of 12 GPS IIF satellites for the U.S. Air Force, will lift off on a United Launch Alliance Delta IV vehicle later this year, with the first launch window in mid-May.
