You can count on us for support long after your purchase. We carry an extensive supply of parts and loaner equipment on hand here in Yorkton for our customers.  We have very strong working knowledge on the various SATLOC systems as well.

Below you will find a great deal of information not only on the product line, but also helpful hints & advice to maximize your SATLOC® experience.

We have assembled a number of details you should know about your system operation.  To see them now, click here.

We can help. We look forward to hearing from you.

Interested in the airplane's on/off capabiliites? Here's an article on work we did with Xarvio.





The Satloc G4™ is the most complete and advanced aerial guidance system for aerial applicators. Built with an Intel® Dual-Core™ i7 processor, the G4 has top of the line processing power and includes Windows® 7 64-bit operating system.  Beyond the basics, this system has many advanced features to support the pilot and to perform autobooms and prescription map work.

If you would like to test fly the G4 from your home computer we can arrange that for you. Email us or call us and we will send you a copy of the G4 simulator.

Featured here is the 9" moving map screen - a 7" screen is also available (same screen as shown in the Bantam picture below).  View Data Sheet


There are still a number of small aircraft in Canada and it is so exciting to have such a snazzy GPS system to offer.  If your needs are basic, but you want a moving map system, this is the unit for you.  

Pictured here is the Satloc 7" screen.  The larger Satloc 9" G4 screen (as seen above) also interfaces to the Bantam if you prefer a larger viewing area.   Yes, this system interfaces with flow control too.  Talk to us about these options. View Data Sheet


The next generation in affordable entry-level GPS guidance

Seen here, the LiteStar IV™ is the next generation entry-level guidance system for aerial applicators. The all-new L7 lightbar and intuitive controller will simplify and improve all types of spraying applications. Simply confirm pattern type and swath width at startup and go to work, or immediately recall the previous job after boot up and go right back to where you left off.

The LiteStar IV includes the L7 lightbar, LiteStar IV controller, A21 antenna and associated cables. View Data Sheet



Intelliflow 2 released November 2017 - legacy unit still avialable while quantities last

With the IntelliFlow™ control system on board, spray rates will be automatically controlled with an accurate constant flow upwind and down.

Also used for variable rate mapping as well as automatic spray on/off. View Data Sheet

If you have flow control, we highly recommend installing an inline strainer ahead of your flow meter and valve. See details here.

Pressure Management Kit

This Yorkton Aircraft addition to your GPS system is designed to help you manage your pump and boom differential.  With flow control this is a must have.  Many don't realize how hard their pump is working and forcing the flow control valve to deal with all that pressure PLUS give you exact target rates.  Read more here.

Laser Altimeters by Ag Laser

The interest in this products reminds us of when Flow Control was first introduced.  Pilots/owners questioned the value in the product.  But those who fly with it now, won't fly without it.  Both flow control and this Laser are tools for the pilot to help him do a job very well and reduce his work load, to keep him fresh.

As one pilot told us:

"When I'm tired I suspected I flew higher.  The laser proved that to me.  Plus at dusk, last of the daylight I always seem to question my spray height given the low light conditions. My Laser Altimeter helps me do a consistent job and helps to keep me safe."

Flow Meter Calibration Adjustments:

The best way to make changes is to work with known quantities.  Know your required quantities, know what went out.

If you want the meter to count faster (put out more) increase your calibration code.

If  you want the meter to slow down (put out less) decrease your calibration code.

In Ag spraying, this is the formula we have relied on for calibration adjustments:

   - What the GPS said / What you know is true * existing calibration number

In Foresty, this is the formula (based on different measurements):.

   -  What is required for the job divided by what you actually used (the  known actual value is always the denominator).
   -  Then times that by the existing calibration number.

M3 software



Is your GPS receiver set to PRN 135? In Canada, this is the most effective WAAS satellite. How to change to this satellite can be found here.

Zoom: To have Intellitrac automatically zoom in/out to keep your pattern in view while spraying, the ZOOM button must be in AUTO mode.

G4 logging at 0.2 seconds - The G4 is very robust, it can handle lots of data. We recommend logging at 0.2 seconds.  The fast airplanes are moving at 60 meters per second logging your position more often greatly improves your return to field accuracy and provides a much more accurate as applied map.

Corrosion induced Intermittent Problems -  The slightest amount of corrosion on a pin, on a fuse, wherever will cause you more grief than you can imagine.  Tug test your cables. Always checking your cables for proper connection by giving them the tug test first before disconnecting so you know you had a bad or good connecction. 

INFO SWATH: tells you many swaths are left to spray in your closed pattern

For our Bantam Friends and for the time when NO Signal dances across your touch screen, this is the button to touch - see the arrow - until you see Analog and your screen will be back. We call the button the dog paw one - first one left of center.



SYSTEM CODES? Do you know what your calibration code is? Your ag laser code? Your autoboom code? Write it down somewhere - we always recommend the front page of the journey log. Or, better yet, placard the dash with these codes. Guaranteed you will need them one day.

RETURN 0: Forgot to mark your last field and you need to return to it? This will take you there.

WHY DID MY SCREEN GO TO A BLACK BACKGROUND? Somehow you pressed, SET SET.  This changes your screen from day to night mode; pressing this again brings it back to day mode.  The dark screen is very good for the end of day flying to reduce cockpit brightness.

INFO INFO: is the short cut key to the Flow Control menu

LOG: pressing the LOG key after you press CLEAR Pattern Enter.  This puts your new field in its own file.  Saves tons of time if you want to go back and review a specific field later.

Prefer RED? You can change your swath line colour, in a G4 to red from blue on the 3rd page of the Options menu.

Forgot to mark your field?: RETURN 0 will take you back to your last spray point, as long as you haven't activated your spray on position since last in the field.

See your as applied map on Google Earth: With the latest Mapstar version you simply open your log file, click the KML button and voila - two google earth files are created - one for your as applied, the other for your ferry and turn displays. The KML files are automatically saved to the same direcotry as your log files.  As long as you have google earth on your computer, once you click the KML file Google Earth will automatically load with your file layed on top.

Memory Sticks along for the ride in your UPS Port: Not a good idea.  Use your memory sticks only for transferring files. Otherwise they can be a pain on boot up and can slow your system down, or even prevent a boot up.

Ferry Flights:  If you have your system set to log at 45 mph, remember even on your ferries the system is logging.  If you are on a lng ferry, you may want to increase this logging speed to a factor above your spped to prevent logging or press LOG & turn logging off.

Cycling your Intelliflow Valve:: in the test valve page change Open Time to 2000, Close Time to 2000 then down below choose OPEN and watch your valve/encoder position. The Legacy Intelliflow open is ~1100, IF2 ~3200 - does it move to this range?  Then choose CLOSE, does position change In Legacy system to 3400-3600, in IF2 system to 6500-6800?  Anything outside these parameters suggests a problem.  If you get no action, make sure your bypass switch is in NORMAL mode, in Bypass your valve will not respond to commands.  Remember to put your OPEN and CLOSE time back to 200 when you are done the cycle, or your valve will not work in flight.

Flow control seems lazy? It could be dealing with too much pressure.  We have lost count of the number of problems solved by installing a pressure gauge to read your pump pressure.  See the details here

Speaking of pressure...using Pressure Switches? If your flow control is using a pressure switch for the spray on/off condition, make sure you have a spare switch on hand.  They gum up easy and will quir working.  You won't see painting on your screen, your acres won't count, no flow monitoring, no control.  It's mid season, if you haven't had trouble, consider changing your switch with a new one. 

Flow Meter Debrisclick here to see what could be causing the issue.

Seeing F1 message? - The internal CMOS battery in your CPU is dying. On average they last 5-7 years. Connect with us to get the right replacement battery. 

Virtual Lightbar: Remember your Satloc has a virtual lightbar! We don't promote head in cockpit so only use in extreme  circumstances. Fly safe! 


Calculator: Did you know your Satloc GPS screen has a calculator on it?


We can send any of this software direct to you. No charge!

Young pilot to senior pilot - "That is the best damn fatigue instrument ever made!"  

Senior pilot says, "What do you mean, I don't have a fatigue instrument on board?" 

Young pilot, "you sure do- it's right there in front of you.  It's called a lightbar!  When I'm fighting to grab my line or can't stay centered, I know it's time to rest!"

This story was told to us by Leif Isaacson, the 2014 NAAA President, when he joined Yorkton Aircraft's new pilot session held at the February 2014 CAAA Conference in Regina.
