Maximize Your Esri Field Maps Precision with Asteri GNSS

While Esri Field Maps is a widely used and powerful tool for mobile data collection, the quality of the spatial data is only as good as the hardware behind it. Relying on the internal GPS of a standard mobile device or an outdated GNSS receiver often results in a 1-meter margin of error. This is often fine for locating a building, but insufficient for locating a buried valve or a specific utility pole.

The Asteri GNSS line of receivers is designed to close that gap. Specifically engineered for seamless integration with the Esri ecosystem, Asteri receivers transform your mobile device into a professional grade high-precision mapping tool.

Why Asteri is the Perfect Match for Field Maps Users

Integrating an Asteri receiver into your ArcGIS workflow isn’t just about getting a better GPS point on the map but data integrity and field efficiency.

• Native iOS and Android Compatibility: Asteri receivers are built to work across all platforms. On iOS, they are MFi (Made for iPhone/iPad) certified, ensuring a stable, high-performance Bluetooth connection that Field Maps recognizes instantly.
• Sub-Meter to Centimeter Precision: With an industry-leading 965-channel receiver, Asteri devices like the X4i deliver unbeatable performance. Whether you need sub-meter accuracy right out of the box or centimeter-level RTK precision, Asteri has a solution that fits your project requirements.
• Full GNSS Metadata Support: Field Maps can capture detailed metadata such as horizontal and vertical accuracy, fix type, and PDOP directly from the Asteri NMEA stream. This allows office staff to perform quality control with confidence, knowing exactly how every point was collected.
• Orbitas Correct Integration: For those requiring the highest level of precision, Asteri receivers pair with Orbitas Correct to provide real-time RTK corrections without the need for complex external setups.

The Accuracy Foundation: Orbitas Correct

While the Asteri X4i delivers incredible results out of the box, the true secret for high-precision workflows is Orbitas Correct. Powered by Point One Navigation, Orbitas Correct delivers centimeter-level RTK (real-time kinematic) corrections directly to your device.

• Seamless Integration: Once applied in Orbitas, the corrections apply automatically, removing the need for extra sign-ins and streamlining your field workflow.
• Nationwide Coverage: Enjoy true nationwide RTK coverage without the hassle of managing local base station logins.
• Platform Agnostic: One of the most significant advantages of the Asteri and Orbitas ecosystem is our commitment to interoperability. Tri-Global Technologies understands that companies operate with a diverse suite of software applications for GIS (Geographic Information Systems), asset management, and CAD (Computer-Aided Design). We also understand the hassle of migrating from one service to another. With that in mind, the Asteri and Orbitas ecosystem is designed to integrate seamlessly with all leading industry software.

Built to Last in the Toughest Environments

Fieldwork doesn’t happen in perfect conditions, and your hardware shouldn’t be treated as a disposable commodity. Asteri GNSS receivers are engineered to thrive where others fail.

• Reliable Performance Under Cover: While many receivers lose their fix under heavy tree canopy or in urban canyons surrounded by tall buildings, the Asteri X4i utilizes 965 channels to maintain high-accuracy positioning in the most challenging conditions.
• Sustainable Repairability: Unlike many competitors who offer no repair options, effectively making their devices disposable if a component fails, Tri-Global Technologies stands behind the longevity of our hardware. We offer comprehensive repair services to ensure your device stays in the field, not in a landfill. Our commitment to repairability ensures that your investment is protected for years.
• Extended Hardware Protection: To further protect your investment, we offer extended hardware warranties that go beyond the standard 1-year coverage, providing peace of mind for your long-term operations.
• Rugged and Wearable Design: Every Asteri is built to be lightweight, rugged, and wearable, with the option to use a soft-sided armband or a backpack for true hands-free mobility in difficult terrain.
• All-Day Power: With long-lasting, field-changeable batteries that can run for up to 20 hours, you can complete a full workday in remote areas without worrying about power. Simply swap the battery and keep your Field Maps session running without interruption.

Asteri X4i vs. Industry Standard

Simple 3-Step Setup

Connecting your Asteri receiver to ArcGIS Field Maps is a straightforward process that takes less than two minutes.

• Pair via Bluetooth: Turn on your Asteri receiver and pair it with your iOS or Android device in the standard Bluetooth settings menu.
• Configure the Provider: In the Field Maps app, tap your Profile icon, select Provider, and add your Asteri receiver as the high-accuracy location source.
• Set Your Profile: Create a Location Profile in Field Maps to ensure the datum transformations between your Asteri’s correction service (like RTK) and your map’s coordinate system are handled automatically.

FAQs

Is it possible to use Asteri GNSS receivers with other GIS software solutions?

Yes, the entire line of Asteri GNSS receivers are designed to integrate with nearly any GIS software environment. With data streaming in the NMEA format, the Asteri X4i is compatible with Orbitas, Diamond Maps Offline, ESRI ArcGIS, Geolantis.360, Milsoft FieldSyte, Partner Field Design, QField, RC Map Engine, and more.

Are there any additional fees or subscription costs to using Asteri?

No, there are no mandatory subscription fees or hidden costs required to use your Asteri GNSS receiver with Esri Field Maps or any other NMEA-compatible software. The cost is the one-time purchase price of the receiver.

The only potential ongoing costs are for optional services:

• Orbitas Correct Subscription: This is an optional service for users who require centimeter-level RTK accuracy.
• Extended Hardware Warranty: An optional plan to extend coverage beyond the standard 1-year warranty.

We believe in complete transparency; the price you see for the Asteri receiver is the price you pay to achieve high-accuracy mapping.

How quickly can I start using my Asteri receiver?

Every Asteri receiver is ready for immediate use. You only need to install the battery and power on the device.

How long does it take to set up Asteri in Esri Field Maps?

Connecting an Asteri to Esri Field Maps can be done in 3 simple steps:

• Pair the Asteri to your phone or tablet.
• Configure the provider in Esri Field Maps.
• Set your profile.

Once these 3 steps are complete, Field Maps will automatically recognize your Asteri device in the future.

What is Orbitas?

Orbitas is a mobile data collection application that comes with a web-based management tool, allowing field crews and office crews to work simultaneously. Orbitas allows geospatial professionals across industries to collect, analyze, and manage data in an intuitive and powerful environment.

Users can set up their own coordinate systems, apply custom configurations, store photos, create templates to increase efficiency, perform calculations in the field, and export data into nearly any format needed to integrate with your existing workflow. Orbitas is compatible with Asteri GNSS receivers, including the Asteri X4i, and can also be used to further enhance your data management in conjunction with other GIS software applications.

What is Orbitas Correct?

Orbitas Correct, powered by Point One Navigation, delivers centimeter-level RTK (real-time kinematic) corrections for GIS, mapping, and staking applications. With true nationwide coverage, competitive pricing, and the ability to easily switch between local and ITRF correction datums, Orbitas Correct provides the precision you need for even your most demanding requirements.
