Falcon SF (Starfire)

The Falcon SF is a fullfeatured GNSS that tracks all major positioning systems satellites. The Falcon SF always produces accurate results which can be used by a whole host of applications. When comined with a base station or VRS network, the Falcon SF produces precise (1 cm + 0.5 ppm) positions, and by using the "Starfire for Life" option, an accuracy of 5 cm can be achieved anywhere on the planet without a base station or correction signal. This is a very unique combination and makes the Falcon SF perfect for remote and difficult areas.
The Falcon SF GPS is not only accurate but also smart. The heart of the Falcon SF is its precise GNSS Onyx™ core that generates superior results. The Falcon SF also has a brain, which is a built-in Arm Processor running Windows 10 or Linux. This gives the Falcon SF the ability to think for itself, log data, run user programs, talk to the cloud, and more.

Communications

UHF, GSM, Wifi and Bluetooth communication links with support for multiple RTK formats allow the Falcon SF rover to work with a variety of base stations and VRS RTK networks.

Starfire for Life

StarFire is a global satellite-based augmentation system (GSBAS) which provides a positioning accuracy of 5 cm on a worldwide basis. The Falcon SF includes a free lifetime license for StarFire. Aside from producing excellent accuracy, StarFire also makes the Falcon SF extremely easy to use because there is no need for base stations, SIM cards or any other communications. Just press the on button and go.

UltraRTK™ and RTK Extend™

The Falcon SF with UltraRTK provides an excellent coverage with baselines of up to 40 km, and protection against communication outages of up to 15 minutes is easily handled with RTK ExtendTM.

Universal GNSS Interface

The Falcon SF has a unique configuration that allows it to be setup and configured to mimic other GPS units and therefore run other software.

Falcon Cloud

Everything collected by Falcon can instantly be backed up to the cloud, where work can be monitored and processing can be started before the GNSS has even left the field. This connection also allows workers to share work as they are surveying and monitoring work that has already been completed.

Built-in Logging

虽然猎鹰SF与大多数工业标准数据记录器和软件兼容，它还具有内置的日志记录。您可以登录在仪器上的数据正确，而不需要一个数据记录器。

猎鹰API

随着猎鹰SF，你可以写你自己的全球导航卫星系统的应用。

Direct Sensor Interface

外部传感器，例如测深仪和电缆探测器，可以与GNSS直接连接。

坚韧和现场准备

The rugged, waterproof and shockproof design, coupled with hot swappable batteries, ensures continuous operations in harsh environments. Designed for all-day use in surveying environments, it includes several I/O options, a 1 watt internal UHF radio, and a removable SD card.

The Falcon SF Onyx engine includes a digital ASIC to handle high-speed signal processing and is equipped with three built-in StarFire receivers / demodulators.
By incorporating the use of GPS (L1, L2, L2C, L5), GLONASS (G1, G2), StarFire L-band, and SBAS (WAAS, EGNOS, MSAS, GAGAN) signals, the Falcon SF Onyx GNSS engine provides proven unparalleled performance even in adverse signal-tracking conditions. Onyx also tracks BeiDou (B1, B2) and Galileo (E1, E5A, E5B), although these signals are not yet used in the navigation solution. The receiver is also equipped with two RF ASICS to accommodate future features such as a separate StarFire antenna and a single-board heading.
Superior interference suppression (in-band & out-of-band), multipath mitigation and measurement accuracy are only a few of the technological advances incorporated into the small Falcon SF receiver. Because the Falcon SF is a multi-frequency receiver, it is virtually immune to ionospheric effects. Falcon SF provides "all-in-view" tracking for all signals.

Navigation: SureNav

• Ensures that the rover will transition from one navigation mode up or down to the next mode smoothly and without position jumps
• The receiver runs a second navigation engine in the background to crosscheck the primary PVT solution
• The receiver can also listen to two correction sources at once and apply the dominant correction
• The receiver takes advantage of statistical data, filtering and certain assumptions to discard outlying measurement data
• Shading and mode transitions will not be followed by position jumps

StarFire: QuickStart

• Reduces convergence time and allows StarFire to pull in instantly, provided that the receiver is on a known position
• Saves users valuable time in the field, increasing productivity
•收敛几乎可以在许多应用中被淘汰

StarFire Over IP

• An optional service to receive StarFire corrections over the Internet
•提供访问星火改正环境下卫星传输是不可用的，如深城市峡谷或非常高纬度地区DeliveryDelivery
• Available delivery modes:
- Once per second (streaming)
- Once per 15 / 30 / 60 seconds
• If you can get an internet connection, you can get StarFire Over IP corrections

星火：快速恢复

•上拉GNSS服务中断后，通过消除在提高现场生产力
• Helps users ride through short GNSS signal outages of up to one minute
• Regains 3 cm StarFire accuracy within two minutes after entering StarFire mode
• When used with Quick Start, users are up and running within 5 minutes, achieving maximum uptime
• Adopts an MBRTK technique
•要求在事件前的状态收敛
• Uses the last pre-event fix state to resolve post-event errors in conjunction with post-event corrections
•重新收敛由于暂时导航损失几乎被消除

Multipath Rejection

• The Falcon SF performs a comparison of Narrow Early minus Late discriminator
• The receiver performs pulse and polarization detection and discriminates anomalies
• Phase error detection between composite signal and direct path signal
• Sub-carrier channel detection
• Receiver & software architecture are coupled with antenna design

Ultra RTK

• Allows RTK operation at a distance of up to 40 km between base and rover
• We have tested Ultra RTK to 75 km – and it works!
• Resolving ambiguities over 40 km takes longer and may fail initially
• Once the rover is at 40 km, the typical error is 3.5 cm
• Customers in need of longer baselines are better off using StarFire standalone
• Long baseline work can be done if the operational needs demand it

RTK Extend

• Allows rover to operate to RTK levels when the RTK correction signal is lost due to range or shading
•当RTK启用星火接收机扩展下降RTK模式时，系统会自动转换到RTK扩展模式
• Base and rover listen to the StarFire signal simultaneously
• Base includes a StarFire offset component
• Rover is compatible with 3rd party base connections
• Requires twice the normal convergence period to maintain RTK levels since the offset is received from the base
• You don’t have to move the base when you lose the RTK signal

星火网络覆盖区域

方法

The StarFire Network is a major advance compared to earlier ground-based augmentation systems because it considers each of the GNSS satellite signal error sources independently. GNSS satellite orbit and clock corrections are calculated using a global tracking network of dual frequency receivers. These corrections are directly transmitted to StarFire receivers via geostationary satellite links, resulting in minimal data latency and worldwide operation.
All StarFire receivers use a multi-frequency GNSS receiver that measures the ionospheric delay for each satellite. Tropospheric zenith delays are calculated from a multi-state time and position model aided by redundant satellite observables.

系统完整性

每个第二，多频GNSS接收机的全球网络经由可靠冗余数据链路到位于加利福尼亚（S.W.，USA）和伊利诺斯（N.E.，USA）两个网络处理中心提供的原始数据。这些接收器绑在最新实现国际地球参考框架的（ITRF）坐标系。星火的主要时间参考耦合到国际原子时间标准。
The network is a fully automated, continuously self-monitoring system overseen around the clock by StarFire Network operators. Orbit and clock corrections from both processing centers are distributed via dedicated circuits with multiple communication backups to three geostationary satellite uplink stations. An independent network of StarFire user equipment continuously monitors system accuracy to ensure maximum reliability.

Reliability

• 99.999% availability
• Extensive monitoring through internal checks
• Realtime monitoring of global positioning results
• Redundancy throughout all segments of the system. Redundant data links, geographically separated processing hubs and dual satellite uplink equipment ensure continuous, reliable positioning. The system is inherently robust with the ability to calculate a full set of corrections even if multiple reference stations become unavailable.

性能

The Falcon SF StarFire GNSS receiver provides an accuracy of under 5 cm horizontally and 10 cm vertically (1 sigma).
Unlike DGPS positions that are relative to the reference station location, StarFire produces absolute ITRF positions anywhere and any time. The StarFire accuracy is independent of the distance to the nearest reference station.
