GPS Corrections and Their General Uses

After many years of precision agricultural use, many questions still exist of what is the correct correction for each operation.  I have listed the corrections available and a brief description of their uses.

Wide Area Augmentation Signal (WAAS) –

Accuracy: < 6-8”

Initialization/Convergence: Standard*

This free service provides performance suitable for agriculture applications in which accuracy and repeatability are not of the highest concern. It's most popular for broadacre crop spraying and tillage applications.

Omnistar XP-

Accuracy: 3-5" (8-12 cm)

Initialization/Convergence: Standard*

An OmniSTAR® service for high-performance broadacre spraying and land-tillage applications in which the vehicle will be operating in areas with open views of the sky at all times. OmniSTAR XP requires a convergence period at startup.  Omnistar XP is most popular for boom shutoff systems on sprayers and tillage applications.

Omnistar HP-

Accuracy: 2-4" (5-10 cm)

Initialization/Convergence: Standard*

An OmniSTAR® service suitable for high-performance broadacre seeding, spraying, and harvesting applications in which the vehicle will be operating in areas with open views of the sky at all times. OmniSTAR HP requires a convergence period at startup.  Omnistar HP is popular for broadacre planting, spraying and harvest solutions.

Trimble’s RTX-

Accuracy: 1.5" (3.8 cm)

Initialization/Convergence: Standard*

The new Trimble® CenterPoint™ RTX™ Correction Service delivers GNSS enabled, repeatable 1.5" (3.8 cm) corrections via satellite or cellular network directly to your receiver anywhere in the world. CenterPoint RTX works with the built-in GNSS receiver in your existing Trimble FmX® integrated display, CFX-750™ display, or AG-372 GNSS receiver.  Trimble’s RTX is becoming increasingly popular with cash crop planting using row controls, side dressing, no-till operations, small veggie crops where size does not dictate RTK investments.

RTK Base or Cellular-

Accuracy: < 1" (2.5 cm)

Initialization/Convergence: < 1 minute

CenterPoint RTK is well suited for row-crop planting, strip tilling, land leveling and other water management applications in which the best horizontal and vertical accuracy is required.  Repeatable accuracy is available anywhere, with cellular/base station systems.  Advancements in base station technologies now allow for no line of sight restrictions, and distances up to 20 Miles.

Agricultural GPS systems are no longer about straight lines, it is about intregration into your operation, your future plans and increasing profitability.  Data acquisition, yield mapping and variable rate application are all becoming main stream to today’s farmers.  Without properly installation, calibrated and training you will not be able to maximize your investment.  Ensure you make the right choices, your yields will thank you.

Awesome, thanks very much Paul.

I will look into it. For a small initial investment, it could improve yields, which would be huge.

Also, the new website looks great.

Generally WAAS is a good starting point for any precision purchase, it can cover some of your less accurate requirements on the farm including some planting, sprayering, manure application and fertilizer spreading all areas where accuracy will have very positive returns in quality and reduced costs of inputs

Great post Paul. 

Which one would you suggest for a starter gps?

The 13-Year Lag: Why Today’s Wheat Breeding Success Depends on Yesterday’s Investment

Wheat varieties are performing better than ever, but a “slow drip” of budget cuts means the next generation of innovation is at a critical crossroads. Wheat varieties that deliver high yields, exceptional quality and strong disease packages are available in abundant choice to Manitoba farmers. This choice and performance are thanks to an often-overlooked wheat breeding innovation system. “Wheat is one of my favourite crops to grow; it can withstand whatever the year throws at it,” says Jocelyn Velestuk, chair of the Canadian Wheat Research Coalition (CWRC). “In past decades that hasn’t always been the case.” There’s lots of variables driving the success of wheat in Western Canada, but Velestuk is adamant that the foundation of that success is our wheat breeding programs. “We can’t take that system for granted and right now, it’s at risk,” she says. While the varieties available today are excellent, the process of plant breeding means those successes are built on efforts made over 1

Rotimi Aluko, professor, University of Manitoba

Rotimi Aluko is a professor at the University of Manitoba (UM) in the Department of Food and Human Nutritional Sciences, as well as director of the Richardson Centre for Food Technology and Research. Originally from Nigeria, he completed his undergraduate and master’s degrees in biochemistry there before earning a PhD in food science at the University of Guelph. He moved to Winnipeg in 2001, where he lives with his wife. Their two children are grown; one lives in Winnipeg and the other is in Alberta. Where did you work before UM? I’ve been here for 25 years, but before UM I worked as a research scientist with Agriculture and Agri-Food Canada (AAFC) in Saskatoon. What got you interested in becoming a professor? From my undergraduate days I was fascinated by my professors, how they taught, carried themselves and were respected in society. I worked as a scientist with AAFC after my PhD, but I was always on the lookout for a professorial position. It had been a longtime goal, so when t

Canadian Cattle Association Statement on Revised Regulatory Approach to the Livestock Traceability Regulations

The Canadian Cattle Association (CCA) is pleased by the Canadian Food Inspection Agency’s (CFIA) announcement that new movement reporting requirements for cattle will not be moving forward while changes for other species will proceed. CCA remains committed to our support for livestock traceability as a core pillar of disease preparedness, market access and confidence in Canadian beef. CCA and provincial member organizations are in the final stages of convening a Task Force to work for producers on a risk-based, industry-led approach to disease preparedness and emergency management and will be making an announcement soon, pending finalization of the Task Force members.

Waterton Biosphere Region seeking input on predator losses

The Waterton Biosphere Region is seeking input from livestock producers who have experienced losses to bears, wolves or cougars between 2021 and 2025. Information collected through the survey will be used to help inform discussions around Alberta’s predator compensation program.  Producers are asked to provide up to five years of data on livestock inventories, overall death losses and predator-related losses. Personal information will remain confidential and will not be shared externally.  The survey is currently open to producers located within the Waterton Biosphere Region and will remain open until the end of June.  The survey is available online:  Producer Data – Predator Losses  Paper copies can also be obtained through local municipal district offices.  Understanding the biosphere region The Waterton Biosphere Region is a biosphere region located in southwestern Alberta. According to the organization, biosphere reserves are traditionally organized into three zones, known a

Wild boar eradication efforts continue across Alberta

Province reports nearly 600 animals removed since 2018 Alberta’s Wild Boar Control Program says efforts to eradicate invasive wild boar from the province are continuing to advance, with nearly 600 animals removed since 2018. In an update shared through the Alberta Invasive Species Council (AISC), the province reported that 595 wild boar have been removed through trapping efforts since the program began, including 108 animals in 2025 and nine more so far in 2026. Tracking progress toward eradication Wild boar are considered one of the most destructive invasive species affecting agriculture in North America due to their ability to damage crops, pasture, fencing, water systems and native ecosystems. They can also pose disease risks to livestock and wildlife populations. “The Wild Boar Control Program is taking some big steps towards eradicating wild boar in Alberta with the support of all our amazing partners,” wrote Hannah McKenzie, Wild Boar Specialist with the Alberta government,
