1.10 Precise Point Positioning

u-blox’ industry proven PPP algorithm provides extremely high levels of position accuracy in static and slow

moving applications, and makes the NEO-6P an ideal solution for a variety of high precision applications such as

surveying, mapping, marine, agriculture or leisure activities.

Ionospheric corrections such as those received from local SBAS

geostationary satellites (WAAS, EGNOS, MSAS)

or from GPS enable the highest positioning accuracy with the PPP algorithm. The maximum improvement of

positioning accuracy is reached with PPP+SBAS and can only be expected in an environment with unobstructed

sky view during a period in the order of minutes.

1.11 Oscillators

NEO-6 GPS modules are available in Crystal and TCXO versions. The TCXO allows accelerated weak signal

acquisition, enabling faster start and reacquisition times.

Table 4: Available protocols

All listed protocols are available on UART, USB, and DDC. For specification of the various protocols see the u-

blox 6 Receiver Description including Protocol Specification [2].

1.12.1 UART

NEO-6 modules include one configurable UART interface for serial communication (for information about

configuration see section 1.15).

1.12.2 USB

NEO-6 modules provide a USB version 2.0 FS (Full Speed, 12Mbit/s) interface as an alternative to the UART. The

pull-up resistor on USB_DP is integrated to signal a full-speed device to the host. The VDDUSB pin supplies the

USB interface. u-blox provides a Microsoft

certified USB driver for Windows XP, Windows Vista and Windows 7

operating systems.

1.12.3 Serial Peripheral Interface (SPI)

The SPI interface allows for the connection of external devices with a serial interface, e.g. serial flash to save

configuration and AssistNow Offline A-GPS data or to interface to a host CPU. The interface can be operated in

master or slave mode. In master mode, one chip select signal is available to select external slaves. In slave mode a

single chip select signal enables communication with the host.

The maximum bandwidth is 100kbit/s.
