StarFire 6000

StarFire™ 6000 Receiver

The John Deere StarFire 6000 Receiver is an enhanced replacement for the StarFire 3000 Receiver and expands on the value that precision agriculture customers have come to expect from StarFire products. The StarFire 6000 Receiver implements an improved antenna, the latest in Global Navigation Satellite System (GNSS) signal processing technology, and a new differential correction signal. All of this new technology adds up to improved performance and uptime as well as lower cost of operation when paired with precision agriculture systems such as AutoTrac™ assisted steering system and John Deere Section Control.

What does repeatability really mean for the user?

Repeatability defines how accurately the receiver can calculate its position over a relatively long time window. Repeatability is measured at the receiver and does not take into account additional error sources such as AutoTrac control system error, ground conditions, or implement drift.
 
In-season repeatability is critical when using AutoTrac for multiple jobs throughout the growing season. One example would be creating AutoTrac guidance lines during planting, then using those same guidance lines to complete subsequent jobs such as side-dressing fertilizer, post-emerge spraying, and harvesting.
 
Long-term repeatability is critical when mapping interior and exterior boundaries for later use as input to John Deere Section Control on planters, sprayers, and fertilizer applicators. Long-term repeatability is also critical for growers that use the same AutoTrac guidance lines over multiple seasons for operations like subsurface-drip irrigation, controlled traffic, or alternating planter spacing between the rows from a previous season.

Avoid waiting for pull-in by using hours on after shutdown and QuickStart

The StarFire 6000 Receiver has two features that reduce the amount of time required to achieve full accuracy, or pull-in, when using SF1 or SF3.
 
Hours on after shutdown is a user-configurable feature that allows the receiver to remain powered on for up to 24 hours (0-, 3-, 6-, 12-, and 24-hour options) after the machine is powered down. If the machine is parked outside and the receiver has a clear view of the sky during this time it will continue to track satellites and retain accuracy.  There is no need for the receiver to complete a new pull-in if the machine is started within this defined period.
 
QuickStart is a feature that can help reduce StarFire pull-in time if hours on after shutdown has expired or is not used. QuickStart works when the machine is shut down and the receiver is able to save a known location (must have a clear view of the sky and good SF1/SF3 accuracy). When the receiver is powered back on it can recover to full accuracy in less than 6 minutes if the machine is not moved during this time window. There is no need for the receiver to complete a new pull-in if the machine is not moved before the QuickStart completes.

The StarFire 6000 Receiver has 252 channels and tracks both GPS (United States) and GLONASS (Russia) satellites. Tracking as many GNSS satellite signals as possible increases the chances of retaining accuracy and performance in challenging areas such as when operating near trees.

Improve uptime with multiple StarFire signal tracking

The StarFire 6000 Receiver is capable of simultaneously tracking correction signals from up to three StarFire correction satellites. The receiver tracks and uses correction signals from all StarFire satellites in view and intelligently chooses one that will deliver the best performance.  When the receiver moves into an area where the primary StarFire signal is blocked such as near a tree line, the receiver will automatically switch to an alternate StarFire signal (if visible) to help maintain accuracy and performance.  Compare this to the previous StarFire 3000 Receiver that was only capable of tracking one StarFire signal at a time and could wait up to four minutes to initiate the switch to the next available signal.
 
With the StarFire 6000, the user gets improved performance and uptime when operating precision agriculture systems like AutoTrac and Section Control in challenging areas when compared to the previous StarFire 3000.

Gracefully coast through StarFire signal outages

The StarFire 6000 is capable of coasting through SF3 signal outages of up to 20 minutes in duration in case the user needs to operate AutoTrac in an area where all StarFire signals are temporarily blocked by trees or other obstructions. Accuracy will slowly degrade over this 20-minute period and will be shown to the operator via the accuracy indicator on the display.

Quickly recover to full accuracy after GNSS signal outages

The StarFire 6000 also delivers a faster and more robust rapid recovery feature, which allows the system to quickly recover to high-accuracy performance after losing track of GPS/GLONASS signals for short durations. This means the user spends less time waiting for the system to recover to full accuracy after temporary shading events, such as turning around near a headland shaded by trees.

Take advantage of RTK Extend™ system for up to 14 days

RTK users have experienced the value that RTK Extend provides when operating in areas where communication with the RTK base station is challenging, such as in hilly terrain and areas with many trees. The StarFire 6000 makes another step change in RTK Extend performance compared to its predecessor, delivering RTK Extend for up to 14 days.
 
A possible scenario to understand this enhanced RTK Extend feature:
 

    1. Machine receiver (rover) is communicating with the RTK base station or network and is running in RTK mode
    2. Time 0 – machine receiver loses communication with RTK base station or network due to an obstruction blocking line of site or due to the machine moving outside of base station coverage:
      • StarFire 3000 – automatically switches to RTK Extend (RTK-like accuracy and repeatability)
      • StarFire 6000 – automatically switches to RTK Extend (RTK-like accuracy and repeatability)
    3. Time - 15 minutes:
      • StarFire 3000 – automatically switches to SF2 Fallback (+/- 5 cm (2 in) accuracy with no repeatability)
      • StarFire 6000 – remains in RTK Extend (RTK-like accuracy with repeatability)
    4. Time - 14 days:
      • StarFire 3000 – SF2 Fallback ends and customer can switch to SF1 if desired
      • StarFire 6000 – RTK Extend ends and customer can switch to SF1 if desired
