End of Life product: z050 USB GPS Dongle with PPS – New product ⇒ z052 USB GNSS Dongle with PPS
z050 Timing and Navigation Module (End-of-Life)
The Pulse Per Second (PPS) is an electrical signal that very precisely indicates the start of a second. The z050 GPS chipset delivers the PPS signal with an accuracy ± 25 nanoseconds (at chipset level).
The z050 USB dongle provides an L1 Frequency GPS receiver, with NMEA protocol from a USB port and also a PPS timing output.
The z050 unit is based on a GPS receiver from Trimble with 22-channel continuous tracking and high sensitivity (tracking -160dBm). With its higher sensitivity, performance and faster startup times, the z050 module is a complete GPS receiver that generates position fixes with high accuracy in extremely challenging environments and under poor signal conditions (down to -160dBm), velocity and time data with leading edge acquisition times.
In addition, the GPS receiver provides a configurable 1 PPS synchronized to GPS/UTC, typically within 25 nanoseconds (one sigma) and an update rate up to 5Hz.
The z050 module is capable of receiving Satellite Based Augmentation System (SBAS) corrections, including the U.S. Wide Area Augmentation System (WAAS) and the European Geostationary Overlay Service (EGNOS). GPS assistance (aGPS) is also supported.
When the USB dongle is connected to your equipment (desktop, laptop, netbook, UMPC …), a virtual serial port is available after installation of the driver by the operating system – for example: USB Serial Port (Com x). Drivers are available which allow the z050 USB dongle to work with the following operating systems:
- Windows Server 2008 R2, Windows Server 2008, Windows Server 2008 x64
- Windows 7 , Windows 7 x64
- Windows Vista, Windows Vista x64
- Windows Server 2003, Windows Server 2003 x64
- Windows XP, Windows XP x64
- Windows 2000, Windows ME , Windows 98
- Windows CE.NET (Version 4.2 and greater)
- Mac OS X, Mac OS 9 , Mac OS 8
For most of these operating systems two types of driver are available: Virtual COM Port (VCP) drivers and direct (D2XX) drivers. The VCP driver emulates a standard PC serial port such that the USB device may be communicated with as a standard RS232 device. The D2XX driver allows direct access to a USB device via a DLL interface. Virtual COM port (VCP) drivers cause the USB device to appear as an additional COM port available to the PC. Application software can access the USB device in the same way as it would access a standard COM port.
The USB dongle contains a USB to serial UART interface and the PPS signal provided by the GPS chipset is connected internally to pin 8 (CTS). So, the PPS signal delivered by the USB dongle is available by using the CTS signal on the virtual com port used.
