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?

Ag Canada Raises Durum Export Forecast; Lowers Ending Stocks

Agriculture Canada has reduced its forecast for Canadian durum ending stocks in 2026-27 amid stronger-than-expected exports, while raising its average price outlook. In its October supply-demand update released Tuesday, Ag Canada lowered projected durum ending stocks by 150,000 tonnes from September to 1.35 million, reflecting an upward revision in expected exports, partially offset by lower anticipated domestic use. Despite the reduction, ending stocks are still projected above the 1.102 million tonnes carried out of 2025-26 and the 512,000 tonnes remaining at the end of 2024-25. Ag Canada increased its 2026-27 durum export forecast by 250,000 tonnes to 5.3 million, down 9% from last year's record but 15% above the five-year average. Meanwhile, expected domestic feed, waste and dockage use was reduced by 100,000 tonnes to 433,000 tonnes, partly offsetting the impact of higher exports on ending stocks. Canadian durum exports have started the crop year strongly, with 787,000 ton

Higher Diesel Prices Put Further Squeeze on Canadian Farm Margins: FCC Report

Record-high diesel prices are putting additional pressure on Canadian farm profitability and transportation costs, with consumers potentially facing higher grocery bills later this year, according to a new report from Farm Credit Canada (FCC). The FCC Economics report examines how elevated diesel prices are affecting Canada's agricultural supply chain, from farm production and livestock operations to transportation, food processing and retail. Using an assumed 80% increase in diesel prices from pre-Iran war levels, FCC estimates Saskatchewan grain producers could see crop margins reduced by $14 to $21/acre, depending on soil zone. That scenario compares diesel at $1.18/litre before the war with $2.13 this autumn. For a 5,000-acre farm, the additional fuel expense would range from $68,000 to $106,000. In Ontario, FCC estimated that an equivalent increase in diesel prices, from $1.28 to $2.30, could reduce corn and soybean margins by $16 to $30/acre, depending on crop and tillage s

Saskatchewan Harvest Virtually Now Complete

Mostly dry weather this past week pushed the 2026 Saskatchewan harvest to near completion. The weekly crop report on Thursday pegged the provincewide harvest at 97% complete as of Monday, up 4 points from the previous week and slightly behind 99% last year. Favourable weather allowed producers to make good progress, leaving only a small number of acres of later-seeded crops still standing, the report said. Harvest is furthest advanced in the southwest and west-central regions, where 99% of crops have been combined. The northern regions are 97% complete, followed by the east-central region at 96% and the southeast at 95%. Most major crops are now almost entirely harvested. Spring wheat, durum, barley, lentils and field peas are all 99% complete, while oats are 98% finished and canola is 96% done. The harvest of fall rye, winter wheat, triticale, mustard and chickpeas is complete. However, some later-maturing crops remain further behind, including flax at 88%, canary seed at 92%,

Understanding and Applying Canola Disease Diagnostic Results

Disease testing through Canola Diagnostic Services can confirm which diseases are present in a field, but knowing how to act on them can be challenging. The real value of diagnostic testing is understanding what those results mean and using that information to make informed management decisions to protect future canola crops. Blackleg and Verticillium In Manitoba Canola Growers’ Diagnostic Testing, blackleg and verticillium stripe results are combined into a single report. For each stem analyzed, the report indicates whether blackleg and verticillium stripe were detected. For verticillium stripe, the report includes an estimated DNA load and an infection category. DNA load reflects the amount of pathogen DNA detected in the sample and can vary depending on plant maturity at sampling. The infection category provides a general indication of disease presence, but it cannot be linked directly to yield loss as the relationship between infection and yield loss is still being researched.
