If you are still using an older GPS or GNSS receiver, there is a good chance you are working with only half of what the sky offers you for accurate positioning. That means you are missing out on a variety of other satellite constellations and more importantly, the FREE, high-accuracy differential correction service now available across Australia and New Zealand through the regional SBAS solution called SouthPAN.
For organisations that rely on accurate spatial data, such as utilities, councils, infrastructure teams, environmental programs and GIS professionals, this is not a small improvement. It represents an important and fundamental shift in how high-accuracy positioning works in Australia and New Zealand. If your receiver cannot use SouthPAN, you are leaving accuracy, productivity, subscription savings, and efficiency on the table. You and your field mapping teams can be achieving so much more and a greater ROI every day.
SouthPAN Is Transforming GNSS Positioning
The Southern Positioning Augmentation Network (SouthPAN) is a government-funded GNSS correction service operating across Australia and New Zealand. It delivers sub-metre positioning accuracy, typically under 50 cm, without base stations, mobile coverage, or subscription fees. The Australian and New Zealand Governments recognised how important mapping is towards productivity and the economy, so they approved the investment that has brought SouthPAN to life for us all – for FREE.
Differential Corrections are transmitted directly via satellite. This allows field crews to achieve reliable and more accurate positioning even in remote environments where mobile coverage is limited or unreliable. For organisations capturing spatial data in the field, this dramatically simplifies workflows.
However, there is one important requirement. Your GNSS receiver must support SouthPAN signals.
Why Many Older GNSS Receivers Cannot Use SouthPAN
Many professional GPS and GNSS receivers currently in use were designed for an earlier generation of positioning technology.
Even though they may still function well, they often cannot take advantage of modern satellite-based correction systems.
This is not a firmware or software update issue. It is a hardware limitation inside the receiver itself. Older receivers may only track a limited number of satellite signals. This prevents them from accessing the full capabilities of modern GNSS infrastructure, including SouthPAN. As a result, organisations using legacy hardware, are operating with reduced satellite visibility, limited range, paying subscription fees that they do not need, and reduced accuracy. In practical terms, they are working with less than half the sky.
Why compromise your data accuracy when collecting field observations when you can easily achieve so much more with a greater ROI?
A New Generation of GNSS Receivers
The EOS Skadi Series was designed specifically for the modern GNSS environment to maximise GIS Field Mapping, data collection speed, and positioning accuracy.
These receivers are built to take advantage of space-based augmentation systems such as SouthPAN for this region. The result is improved positional accuracy and better projection and datum integrity.
For GIS professionals and Spatially enabled field services teams, this means:
- Reliable sub-metre accuracy using SouthPAN corrections
- Improved satellite coverage, access, and signal reliability
- More efficient data capture workflows to prevent repeat visits or post-processing
- Greater confidence in field-collected spatial data to be right the first time
This is particularly valuable for teams working with modern GIS and mapping platforms for above and below ground infrastructure, cultural heritage and environmental management.
If you use ESRI Field Maps, QField, Global Mapper or virtually any mobile GIS mapping software, upgrading your GNSS receiver can dramatically improve the quality and reliability of your spatial data capture and increase the productivity of field and office teams.

Special Offer for Trimble Catalyst DA2 Users
Organisations currently using Trimble Catalyst DA2 receivers may also be eligible for trade-in which will save you ongoing subscription fees.
If an organisation trades in five or more DA2 receivers in a single transaction, a trade-in allowance of:
$500 AUD per receiver ex GST
can be applied to enable the purchase of, either:
- Skadi 100
- Skadi 200 (RTK)
- Skadi 300 (RTK)

This GNSS upgrade path can help GIS enabled organisations eliminate ongoing correction subscription costs while improving positioning performance and speed to data acquisition they can trust from each site.
Additional Eligible Upgrade Options
Eligible trade-ins can also be applied toward:
Skadi Gold Basic Kit
No multi-frequency and no RTK. This can be upgraded in the future via activation code if required.
Skadi Gold HAS Kit
No RTK. This can also be upgraded in the future via activation code if required.
Trade-in allowance
$500 AUD
Important Trade-In Conditions
Trade-ins must be applied on a one-for-one basis.
For example:
Two eligible Trimble RTK units cannot be traded for one Skadi receiver.
Two eligible Trimble receivers can be traded for two eligible Skadi receivers.
