Aerial view of a construction site with several yellow excavators, dump trucks, and ground penetrating radar equipment moving dirt and gravel on large, brown, sandy terrain.

Ground Penetrating Radar: Everything You Need To Know [2026]

June 19, 2026

TL;DR: Ground penetrating radar (GPR) images what’s buried underground using radar pulses, and pairing it with RTK-corrected GNSS positioning turns those scans into centimeter-accurate, georeferenced data instead of rough estimates.
Ground-penetrating…

A blue industrial water pipe system with valves, identified by an underground utility locator, is partially buried in a trench dug in the dirt at a construction site.

Underground Utility Locator Guide [2026]

June 5, 2026

There’s at least one underground utility strike in the United States every minute, resulting in significant damage to well-being and properties, financial loss, and service disruptions. Underground utility locators minimize…

Diagram showing two cars: the top car with a red, curved dashed line labeled loosely coupled GNSS, and the bottom car with a green, straight dashed line labeled tightly coupled INS.

Loosely Coupled vs. Tightly Coupled GNSS/INS: How Integration Depth Affects Accuracy

June 1, 2026

Learn about the differences between loose and tight coupling in GNSS, and why tight coupling provides greater precision to power more reliable solutions.

A group of construction workers wearing safety vests and helmets stand and talk on a large building site with exposed concrete, rebar, green piping, and discuss underground pipe location in the background.

Underground Pipe Location Guide [2026]

May 24, 2026

Accurate underground pipe location is critical for engineers and construction teams to avoid damaging existing infrastructure, minimize the risk of costly repairs or accidents, and ensure the safety of both…

A small, autonomous delivery robot with four wheels navigates a paved path next to greenery and a white fence, using shared maps to understand its location context under the sunny sky.

Location Is Context: Why Shared Maps Are the Missing Infrastructure Layer in Physical AI

May 21, 2026

TL;DR: Physical AI is broader than robotics, but robotics is where the hard problems live. The outdoor location problem is largely solved. Indoors is a patchwork. The real challenge is…

A world map at night with illuminated city lights and glowing points connected by curved lines, representing global communication or network connections across continents using ITRF reference points.

ITRF: What is the International Terrestrial Reference Frame? [2026]

May 20, 2026

The International Terrestrial Reference Frame (ITRF) is a reference frame for earth sciences and global positioning derived from the International Terrestrial Reference System (ITRS). The ITRF is approved by the…

A black rounded rectangle labeled SENSOR FUSION is centered on a dotted green and beige background, with four dashed arrows pointing inward from the top, bottom, left, and right.

The Navigation Engine: Correcting Imperfect Sensors in Real-Time

April 29, 2026

TLDR: Pre-processing prepared your measurements. Time synchronization aligned them to a common time base. Now what? The navigation engine is where sensor fusion actually happens—combining noisy GNSS, drifting IMUs, and…

Calibration Guide: How INS & RTK Calibration Works [2026]

April 22, 2026

Advancements in location technology have catalyzed fields from agriculture to surveying and automated vehicles. From inertial navigation systems to RTK technology, ultra-precise location information has unlimited applications. However, sensors can…

A dark-themed map showing dense clusters of blue circles across the United States and Europe, indicating rtk networks or data points. The map also displays a vertical toolbar with several icons on the right side.

What Is an RTK Network? RTK Network vs. Network RTK Explained

April 20, 2026

TL;DR: An RTK network is the physical infrastructure of reference stations that generates GNSS corrections. Network RTK is one method of computing them, interpolating a virtual reference station from several…
