GNSS IoT Positioning: From Conventional Sensors to a Cloud-Based Solution

The advent of the Internet of Things (IoT) has considerably increased the number of services and applications that require positioning information. In this sense, IoT positioning sensors usually obtain and deliver their position to a central node where it is further managed and analyzed by a user or scheduler. Nonetheless, the stringent requirements of low-cost IoT sensors in terms of low power consumption to achieve larger battery lifetime are pushing current technologies to their limits.

The Cospas-Sarsat MEOSAR System: A Solution to Support ICAO GADSS Autonomous Distress Tracking Recommendation

Today, it appears that the Cospas-Sarsat MEOSAR system, relying on payloads deployed on GNSS constellations (Galileo, GPS, GLONASS), offers all the conditions to meet the new recommendation of ICAO for ADT-system for Commercial Aviation, with a new generation of in-flight triggered beacons, identical to the current ELT in terms of aircraft integration, but capable of receiving triggers and cancellation events from the avionics, from the crew or from internal sensors, and of detecting and managing their inhibitions to maintain the capability to raise alerts and be localized in any situation.

GNSS Hotspots

1. Last Remaining Peatlands
County Kerry, Ireland

√ Ireland is known for its lush green wetlands and raised bogs, also known as peatlands. But most of these areas have been lost due to drainage associated with peat cutting or conversion to agricultural land, according to Wetland Surveys Ireland (WSI). There’s a big push from Europe to conserve the remaining peatlands

The Persistence of Quality

After spending a career as a GNSS advocate and critic, technical interpreter and PNT raconteur, our colleague, Glen Gibbons, begins his transition to Editor Emeritus status this month. And while his daily GNSS activities cease, his contribution for thoughtful analysis, cogency and a reasoned perspective are retained—his imprimatur, gratefully accepted.

What is navigation message authentication?

Q: What is navigation message authentication?  

A: As of today, all open civil GNSS signals are transmitted in the clear, conforming to interface specifications that are fully available in the public domain. Receivers will accept any input that conforms to the specifications and treat it as if it came from a GNSS satellite. Combined with the extremely low power levels of GNSS signals this makes it almost trivially simple to spoof a GNSS receiver.

Spectral Transparent Adhesive

In the past two decades, satellite navigation systems have undergone great development. The development of new generations of global navigation satellite systems (GNSS), represented by GPS III, Galileo, and the BeiDou global system (BDS), is rapidly advancing.

Unfinished Business

All good things must come to an end. At which point, if Fortune smiles on us, other good things begin or continue.

Case in point: as of year-end 2017 I am promoting myself to Editor Emeritus of Inside GNSS and turning to some unfinished business that I have with life. Of course, after 28 years I still have some unfinished business with GNSS, this amazing technology and industry that has more growth ahead of than behind it, more prospects for innovation, more unfinished business than ever.
