Over 900 million GPS receivers are found in assets across America¹. Industries who rely on this technology alone risk problems with operational integrity, as GPS/GNSS signals are increasingly vulnerable to signal interference, outages, inaccuracies, jamming and spoofing.
What is APNT?
Assured positioning, navigation and timing (APNT) solutions deliver precise location, data and time synchronization from the GPS satellite constellation. When GPS/GNSS becomes unavailable, an alternate solution is needed to maintain critical operations. APNT solutions enable seamless and continuous operation for systems that use GPS—ensuring reliable access to accurate location, navigation and timing information in situations that require it.
3 Reasons to Use an Alternate APNT Solution
Maintaining operational integrity often requires fitting solutions into other small devices or not adding additional weight. Measuring as small as two square inches, NAL offers APNT solutions that are low size, weight, and power (SWaP) modules and easily embed into existing infrastructure. For cost-effective operations, products such as SHOUT nano 500 are fully integrated with Alternative, Location and Timing Modules (ALTM) and GNSS receivers, resulting in fewer equipment needs.
GPS/GNSS signals used indoors or in remote environments can be obstructed or limited. Seamless coverage is important when it comes to critical infrastructure, transportation systems and defense operations. APNT solutions must ensure continuous and accurate timing and location data for high-value assets. NAL’s ALTM modules, for example, are powered by Iridium Satellite Time and Location® (Iridium STL®). This 100 percent global service is built specifically to overcome GPS/GNSS vulnerabilities by leveraging a signal approximately 1,000 times stronger than GPS/GNSS, which can penetrate indoors and other GNSS-obstructed areas.
Whether you’re managing a fleet of autonomous vehicles, overseeing logistics in contested military environments, or navigating shipping vessels, APNT solutions need to be truly versatile and customizable for your industry-specific operation.
As industries become more dependent on GPS/GNSS, a reliable alternative APNT solution and strategy are necessary for maintaining situational awareness and essential timing.
NAL Research is the leader in global satellite communications, with APNT solutions designed for mobile users and systems with demanding SWaP constraints. NAL’s advanced and compact APNT solutions integrate into a variety of applications and devices for uninterrupted performance. With a family of low-SWaP ALTM modules powered by Iridium’s global satellite network, NAL offers continuous access to accurate location, data and time synchronization in GPS/GNSS-vulnerable environments.
