Assured position, navigation & timing - when GPS is jammed, denied or spoofed

GPS denied.
Mission intact.

iDvera's ALIS delivers physics-native positioning that keeps working where GPS can't - indoors, underground, and in contested environments. It runs on the sensors already in your platforms and devices. No satellites, no new infrastructure, nothing an adversary can jam.

How ALIS works

Not breaking physics. Giving it more to work with.

Most location systems assume GPS, Wi-Fi or cell towers are telling the truth. When those signals are jammed, spoofed, blocked or just wrong, everything built on top of them fails. ALIS starts from physics instead - using the physical world as its reference frame and fusing it with sensor data your platforms already produce.

PRINCIPLE / ANCHOR

Physics as the anchor

ALIS treats the physical world as the starting point, not an afterthought. If a claimed location would require the laws of nature to be wrong, ALIS treats it as suspect - regardless of what GPS, Wi-Fi or the app says.

PRINCIPLE / SENSORS

More signals, same devices

ALIS works with sensors that already exist in modern platforms and gets stronger as you add channels. It can run on a baseline sensor set alone, or pull in additional signals to refine position and stability - one engine, plug-in channels.

PRINCIPLE / ASSURANCE

Position and assurance, not just coordinates

For each burst of readings, ALIS converges on likely locations and assigns confidence to each - a position that holds in GPS-denied environments, plus a trust signal your systems can act on.

Mission areas

Where trusted position is mission-critical

iDvera goes deep in the markets where a wrong position carries real consequences. Drones, defense and government lead our focus today, and the same physics-native engine already serves critical infrastructure, logistics, identity and financial customers.

01 / Drones & autonomous systems

Navigation that survives jamming, spoofing and GPS denial

Unmanned systems are only as reliable as their position source - and GPS is the first thing an adversary takes away. ALIS gives UAS, UGV and autonomous platforms a physics-native position derived from onboard sensors and the physical environment, so missions continue when satellite navigation is jammed, spoofed or simply unavailable.

  • GPS-denied navigation for UAS in contested or degraded airspace
  • Spoofing detection and position cross-checks for BVLOS and autonomous flight
  • Indoor, underground and urban-canyon flight where satellite signals never reach

02 / Defense & government

Mission-critical positioning for contested environments

Defense, federal and public-safety teams operate indoors, underground, in urban canyons and in contested areas where GPS is unreliable, denied or actively hostile. ALIS provides a position and a confidence score that hold up in GPS-denied environments - supporting command-and-control, accountability, mission planning and after-action review.

  • Alternative PNT for platforms and dismounted teams in jammed environments
  • First responder and team positioning inside buildings and complex structures
  • Search and rescue coordination in GPS-denied or degraded environments
  • Location assurance for secure facilities, personnel accountability and audit

03 / Critical infrastructure & OT

Secure operations in GPS-denied environments

Energy grids, water systems and industrial facilities increasingly face GPS jamming, spoofing and outages where safety and uptime matter most. ALIS provides GPS-independent positioning for crews and assets, so OT teams can see where work is really happening and cross-check it against the physical world.

  • Substation, pipeline and facility access verification independent of GPS
  • Field crew location documentation for safety and audit
  • Underground and indoor facility positioning for critical operations

Company

About iDvera

iDvera exists because our founder watched a "trusted" location story fall apart. While consulting for a SaaS company, he was asked to quietly validate two new hires who were supposed to be based in Chicago. Their schedules looked identical, they were often offline at odd hours - and every digital signal (VPN, device checks, IP-based location) still said "Chicago."

One day both accounts briefly came online without the usual VPN, revealing they weren't in Chicago, they weren't within CONUS as required, and they weren't even two people - it was one individual posing as two employees from overseas.

That experience raised a simple question existing tools couldn't answer reliably: "How do you know someone is where they say they are?" iDvera was started to answer it. Greg, the founder and inventor of ALIS, spent several years developing the physics-native technology behind the system. As it matured, his father Dr. Samuel Steinberg joined as co-founder, and in 2025 Stephen Kaniewski, former CEO of Valmont Industries, joined as co-founder - bringing deep experience in industrial infrastructure, global operations and customer relationships.

Today the team is evolving ALIS into both a verification layer and a positioning capability that operates even when GPS and common wireless signals are missing, jammed or untrustworthy - so "where" can stand as a signal organizations can actually trust.
