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?

Welcoming Visitors: Show Off Your Herd Safely

Welcoming visitors onto your beef operation for tours, sales or informal stock viewings is a great way to connect and tell your story, but it also opens the door to a serious risk: disease. Every visit—whether from neighbours, tourists or family—carries the potential to introduce or spread disease to or from your operation. Good biosecurity practices help manage these risks while also reducing the probability of disease at the herd, national and even international levels. It’s important to understand why biosecurity matters during tours, as well as what actions should be in place before, during and after tours to minimize risk. Why Biosecurity Matters During Tours Biosecurity planning and precautions should be implemented during tours to limit the potential spread of disease to your livestock. This not only helps protect against significant reportable and trade-limiting diseases such as Foot and Mouth Disease, but also helps reduce the spread of endemic diseases, such as bovine viral

CWRC review of Canadian wheat breeding innovation system confirms significant gaps and risks

The Canadian Wheat Research Coalition (CWRC) has completed its review of the Canadian wheat breeding innovation system. The review, which was conducted by Synthesis Agri-Food Network, featured comprehensive analysis of related reports and studies, as well as interviews with 29 key stakeholders. This process confirmed three crucial facts about the current wheat breeding landscape in Western Canada: 1. The Agriculture and Agri-Food Canada (AAFC) wheat breeding program is an integral part of western Canadian wheat variety development. 2. The current wheat breeding system is at risk from recent and historic budget cuts, especially at the variety development and pre-market evaluation stages. 3. Wheat breeding is a long-term process and decisions made today will impact agriculture decades into the future. “It’s clear that the status quo is not a viable path forward,” says CWRC chair Jocelyn Velestuk, CWRC chair and a farmer near Broadview, SK. “Our system has been incredibly productive

Protein Industries Canada partners with nine companies to boost domestic food production and strengthen Canada’s food supply chain

Today, Protein Industries Canada announced the second cohort of companies participating in its Strengthening the Canadian Supply Chain Program: nine companies that span the value chain, focused on bringing their supply chains home to Canada and advancing the country’s value-added opportunity. This initiative builds on Protein Industries Canada’s efforts to increase domestic food and ingredient processing as a key market for Canadian crops. By working with companies to Make It Here, Protein Industries Canada is driving increased food production and value-added agriculture in Canada—critical factors for strengthening Canada’s supply chain and economy. “The Government of Canada is committed to shifting Canada’s economy from reliance to resilience—building strength at home and reinforcing the supply chains that secure our prosperity,” said the Honourable Mélanie Joly, Minister of Industry and Minister responsible for Canada Economic Development for Quebec Regions. “Through Protein Indust

Rollins, Vaden, and Forst Announce Disposal of Dilapidated USDA Facilities

Today, U.S. Secretary of Agriculture Brooke L. Rollins and Deputy Secretary Stephen A. Vaden, joined by General Services Administrator Edward C. Forst, announced the imminent disposal of the South Building and Braddock Place, returning resources to the American taxpayer, effectuating the vision of President Donald J. Trump, and reducing the real estate footprint of the U.S. Government in the National Capital Region. “This is a long overdue move to protect American taxpayer dollars from being wasted on expensive real estate inside the Washington, D.C. area when our government should be closer to the farmers and ranchers we serve,” said Secretary Brooke Rollins. “More than 85 percent of the South Building is unoccupied and there is a $1.6 billion backlog in deferred maintenance. It is simply unacceptable to put these costs on the taxpayer. We are being strong stewards of taxpayer dollars while also ensuring top notch customer service and fulfilling our promises to American farmers.” “P
