The choke plate hardware in the StarFire 7000 Receiver more accurately directs GNSS signals into the antenna. Areas with thick tree lines or obstacles that could cause shading of the receiver.
RTK Radio may still be required in the following scenarios: NOTE: SF-RTK uses satellite corrections only and does not require the use of an RTK Radio. Repeatability defines how accurately the receiver calculates its position over a relatively long-term window. NOTE: 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 4 minutes to initiate the switch to the next available signal. When the receiver moves into an area where the primary StarFire signal is blocked, such as near a tree line, the receiver automatically switches to an alternate StarFire signal (if visible) to help maintain accuracy and performance. The receiver tracks and uses correction signals from all StarFire satellites in view and intelligently chooses one that delivers the best performance. The StarFire 7000 and StarFire 7000 Integrated Receivers simultaneously track correction signals from up to three StarFire correction satellites. The SF-RTK signal uses two additional satellite constellations (BeiDou and Galileo) as well as both GPS (United States) and GLONASS (Russia) satellites. This is an improvement of 17 percent from the previous generation of StarFire receiver. The SF-RTK correction level provides 2.5-cm (1-in.) horizontal accuracy without the need for additional hardware. The StarFire™ 7000 Receiver offers a new correction level with accuracy like RTK Radio.
