GPS-independent positioning and location assurance

GPS denied.
Mission intact.

iDvera's Advanced Location Intelligence System (ALIS) provides physics-native positioning when satellite signals fail, are jammed, or cannot be trusted. It runs on sensors already in your platforms and devices. No new beacons or transmitters required.

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

When the sensor evidence is strong enough, ALIS returns a position and an uncertainty estimate. When the evidence is weak, outdated, or conflicting, it flags the limit and withholds a position it cannot support.

Talk to engineering

Drones and UAS

Drone navigation that does not depend on GPS.

ALIS gives unmanned aircraft a second navigation source. It estimates position from onboard sensors and stored geophysical references, reports how far that position can be trusted, and hands both to the autopilot you already fly.

AutopilotCube / ArduPilot keeps control
GNSS dependenceNone after initialization
Flight dataShared under NDA

Operating modes

Two ways to fly ALIS.

Add ALIS as an independent second source alongside GNSS, or make it the source the aircraft actually flies on.

Mode 1

Redundant navigation

ALIS runs alongside GNSS as an independent second navigation source. GNSS is kept out of the ALIS solution, so a GNSS problem does not carry into ALIS, and you can see when the two disagree.

  • Continuous position estimation without ongoing GNSS aiding
  • Evidence-based corrections from fresh sensor observations
  • Explicit uncertainty with every position
Mode 2

Primary navigation

In flight, the autopilot hands navigation over to ALIS. The aircraft keeps flying its route on ALIS position while Cube / ArduPilot continues to handle stabilization and motor control.

  • Manual or automatic source handover
  • Route and waypoint following on ALIS navigation
  • Defined response when evidence weakens: qualify, hold or fall back

Integration

Fits the autopilot you already fly.

ALIS is a navigation input, not a replacement autopilot. There is no new flight stack to adopt and no beacons to install.

External navigation input

ALIS delivers position and uncertainty through the external-navigation path ArduPilot already supports.

In-flight source switching

Hand over from GNSS to ALIS and back during flight, commanded by the pilot or triggered automatically.

Uncertainty the autopilot can act on

When the supporting evidence is thin, ALIS says so instead of reporting a confident wrong position.

Onboard sensors and stored references

Magnetic, inertial and pressure measurements matched against geophysical reference data carried on the aircraft.

ArduPilot references: external navigation and source transitions.

Evaluation

Performance you can verify.

Every ALIS evaluation is scored against an independent reference on the six measures that decide whether a navigation source can be trusted in flight. Full results are available under NDA.

Position error

Measured difference from the evaluation reference, with its full distribution.

Reported uncertainty

The confidence region ALIS reports, and how often the true position falls inside it.

Availability

How often an accepted position is available across the flight.

Continuity

Uninterrupted accepted intervals and the longest continuous run.

Track following

How closely the aircraft holds its commanded route on ALIS navigation.

Time without GNSS

The verified interval flown with no GNSS aiding in the solution.

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. The same engine is also being prepared for infrastructure, logistics, identity and financial operations.

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

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.
