3vG and NISAR: Your questions answered

How 3vG and NISAR Technology Can Help You Monitor Ground Movement Smarter

3vGeomatics (3vG), part of Orica Digital Solutions Geosolutions portfolio, understands that their customers require reliable and cost-effective methods for monitoring ground movement, particularly across remote, vegetated, or expansive infrastructure networks. That’s why they’ve integrated data from NISAR, the NASA–ISRO Synthetic Aperture Radar satellite, into their monitoring services.

Here’s how it works and why it will help you:

What makes NISAR different from other satellites? 

NISAR (NASA–ISRO Synthetic Aperture Radar) is the first satellite to use dual radar frequencies: L-band and S-band, to systematically map Earth’s surface. Its L-band radar has a longer wavelength (~240 mm), which allows it to penetrate vegetation and soil, detecting even subtle ground movement in areas where traditional InSAR methods can’t reach.

How often does NISAR collect data?

NISAR revisits the same location every 12 days, capturing large image footprints across global landmasses. This means you receive regular, reliable updates, ideal for tracking change over time and responding quickly to emerging risks.

Is the data accessible?

Yes. NISAR follows an open data policy, so raw SAR imagery is freely available. 3vG processes this data using advanced algorithms to generate InSAR outputs and clear, actionable insights into displacement and acceleration.

What problems does it solve for my operations? 

NISAR helps address several key challenges:

• Vegetated and remote terrain: L-band radar penetrates dense vegetation, enabling monitoring in areas previously inaccessible
• Network-wide coverage: Monitor entire infrastructure systems, including pipelines, roads, railways, and power distribution networks, not just isolated segments
• Risk management: Detect ground movement early, respond faster to geohazards, and meet regulatory requirements
• Cost efficiency: Scalable, reliable data without the high price tag of commercial satellites.

What will I receive? 

With 3vG’s NISAR-powered service, you receive:

• Fast, regular updates to detect risks early
• Coverage across entire networks, no matter the terrain
• Reliable monitoring in harsh environments, vegetated slopes, remote sites, and long infrastructure corridors
• Actionable insights that support safety, compliance, and smarter planning.
