U.S. Air Force Gets Another GPS Satellite into Space

The United Launch Alliance successfully launched another U.S. Air Force GPS Block IIF satellite at 2:36 p.m. EDT today (March 25, 2015) from Cape Canaveral on board a Delta IV rocket.

The Air Force Second Space Operations Squadron (2 SOPS) indicates that IIF-9 (identified by space vehicle and pseudorandom noise code, respectively, as SVN-71/PRN-26) will replace SVN-35 (currently being operated in Launch, Anomaly Resolution and Disposal Operations or LADO status) in the B plane slot 1F.

KCS TraceME RF Positioning Enhancement Targets IoT Apps

KCS TraceME RF Positioning Enhancement Targets IoT Apps

TraceME with LoRa module

KCS BV, based in Dordrecht, Netherlands, has extended its TraceME product line with an advanced module, targeted for worldwide mobility in the Internet of Things  (IoT) era.

The latest development of the TraceME GPS/GPRS Track and Trace module will incorporate an RF location–based positioning solution with LoRa technology. According to the company, this combination enables “smart objects” to become even smarter, because LoRa enables long-range, battery-friendly communication in a wide variety of machine-to-machine (M2M) applications.

Flying Blind

It’s 10 p.m. somewhere over the vast oceans that comprise three-quarters of the Earth’s surface. Do you know where your airplane is?

Well, you could, but maybe you don’t.

The anniversary of the disappearance of Malaysia Airlines flight MH370 came and went in March with the fate of the Boeing 777 still unknown.

It didn’t have to happen.

GAO Report: More Delays, Cost Increases for OCX, GPS III

New delays and higher costs should be expected for both the GPS III satellite program and GPS-OCX, the new GPS ground system, federal watchdogs warned in a new report.

The Government Accountability Office (GAO) said both programs are in the process of rebaselining, that is, resetting their estimated schedules and costs. In the case of the Next Generation Operational Control System (GPS OCX), which is essential for full operation of the new GPS III satellites, the changes could be significant.

Two agencies charged with helping protect America’s critical infrastructure are working on ways to safeguard GPS receivers, particularly those used to tap the signal for essential timing data.

The Department of Homeland Security (DHS) is building on its more recent, technically focused research to identify and mitigate risks.

Renewed Spectrum Fight Emerges between GPS, LightSquared at ABC Workshop

Spectrum-related tensions reemerged during a workshop on Thursday (March 12, 2015) organized to gather feedback on a testing plan to help protect GPS receivers.

The plan is part of the GPS Adjacent-Band Compatibility (ABC) assessment — a wide-ranging effort to determine the power levels at which services operating in frequencies next those used by GPS and other GNSS systems can broadcast signals without causing interference to GPS signals.

GNSS and Precision Farming

GNSS and Precision Farming

Dr. John Fulton, Ohio State University

Nowhere has the fact that GNSS can guide things besides military weapons and transport manifested itself more profoundly than in agriculture.

While Google and automotive manufacturers struggle to figure out how to put autonomous vehicles on the highway, farmers have been using GNSS for well over a decade to guide equipment through their fields — along with a host of other ag-related, site-specific applications.

Indeed, GNSS — along with an array of other high-tech resources — is transforming agriculture at an accelerating rate.
