What is ProFlex 800 CORS?
ProFlex 800 CORS is a rugged and high-performance CORS
reference station. Designed as an extension of the ProFlex
800 receiver, ProFlex 800 CORS integrates the best of
today’s technologies, including the exclusive Z-Blade™
algorithms and multi-constellation (GPS+GLONASS+
GALILEO+SBAS) capabilities.
The main features of ProFlex 800 CORS are the following:
• Embedded Z-Blade technology guarantees outstanding
quality, availability and reliability of raw data acquisition,
providing the best possible measurements from four
GNSS constellations: GPS (including L5), GLONASS,
SBAS and GALILEO.
• Extended internal memory (8 Gbytes) for data storage.
• Embedded and password-protected Web Server giving the
owner full remote control of the reference station via an
Internet connection. The Web Server returns web pages on
the owner’s computer that give the owner the capability to
monitor the operation of the reference station, or change
partially or completely its settings.
• Generation of raw data files entirely manageable through
the Web Server. Data recording is organized as sessions,
with preset duration, ensuring round-the-clock data
recording, day after day and year after year.
• Raw data files can be converted to Rinex 2.11, Rinex
3.01, Hatanaka or TarZ before being made available to
users. RINEX conversion is performed on the fly (RINEX
file is available immediately after a session is finished to
meet rapid and ultra-rapid IGS services requirements). Up
to two RINEX files with two different periods can be
generated simultaneously.
• Embedded Ring File memory function offering unlimited
use of the storage medium. Enabling this function will
allow the oldest files in memory to be automatically
deleted if necessary to provide storage space for current
files being recorded.
• Raw data files can be pushed automatically to an external
FTP server. A backup FTP server can also be planned,
either as a fallback FTP server in case the primary FTP
fails, or as a second repository for data files.
•Embedded NTRIP caster (firmware option) offering the
possibility of implementing a complete network service
according to the NTRIP protocol. Using this protocol

2
makes it possible to access various sources of data from
different base stations through a single Internet
connection, as well as efficiently protect these sources of
corrections from unauthorized users.
The embedded NTRIP caster allows you to organize a
network of up to 10 different mount points (each of them
receiving corrections from an NTRIP server) and up to 100
users given the ability to receiver corrections through
these mount points.
• Smooth integration of meteorological and tilt data. Meteo
and tiltmeter sensors fully controlled by the receiver.
•Embedded FTP server allowing the administrator to
perform maintenance steps remotely or allow authorized
users to download raw data files directly from the receiver.
• Automatic email notifications informing the administrator
of possible malfunctions in real time.
• High degree of flexibility inherited from the ProFlex 800
receiver. In addition to delivering raw data files in ATOM
or Rinex format, the ProFlex 800 CORS can deliver
simultaneously real-time RTK corrections in ATOM
(configurable), RTCM2.3, RTCM 3.0 & 3.1 or CMR format
through various means:
– As an IP server or client delivering different streams of
raw data through up to nine virtual IP ports (Ethernet
data streaming).
–Asan“NTRIP Server”, delivering its corrections to the
embedded NTRIP caster (firmware option) or to an
external or third-party NTRIP caster. Up to two
independent NTRIP servers can be set up in the
ProFlex 800 CORS.
– Through Direct IP
– Through a UHF radio link
– Through its built-in GSM modem.

Equipment Description & Basic Functions
Front View
From left to right:
Bluetooth Antenna. A coaxial female connector (reverse SMA
type) allowing you to connect a Bluetooth antenna for
wireless communication with a field terminal or other device.
Cellular Antenna. A coaxial female connector (SMA type)
allowing you to connect a cellular antenna. A cellular antenna
is required when the ProFlex 800 sends or receives RTK or
differential corrections data via its internal cellular modem
(GSM).
Take care not to swap the Bluetooth antenna and the cellular
antenna. The picture below shows where the shorter and
longer antennas should be connected.

6
USB Host & Device. A nine-contact female connector (Fischer
type). Depending on how it is configured, the USB port can
be used in two different ways:
1. For a USB host, such as a mass storage device using
optional device cable P/N 702104.
2. For a USB device allowing ProFlex 800 to be seen as a
disk from the computer connected to this port. In this
configuration, files can be transferred between the
ProFlex 800’s internal memory and the computer using
the USB cable provided (P/N 702103).
Display Screen. The display consists of a 128 x 64-pixel, 1.5-
inch monochrome yellow screen using organic LED
technology (OLED).
Used in conjunction with the Scroll button, the display screen
allows you to view different pages of information. See Display
Screens on page 1for a detailed description of the
information available from this screen.
After a few seconds of inactivity (i.e. Scroll button idle),
screen luminosity turns from high to low level.
Power button. To turn on the ProFlex 800, hold the Power
button pressed until the power LED lights up.
To turn off the ProFlex 800, hold the Power button pressed
until the “Ashtech” screen is displayed. Then release the
button and wait until the ProFlex 800 shuts down.
Power LED. •This indicator light is off when the ProFlex 800
is off and no external power source is connected to the DC
power input.
• It is on and red when an external power source is present
at the DC power input and the ProFlex 800 is off.
• It is on and green when the ProFlex 800 is on, regardless
of whether it is powered from the internal battery or an
external power source.
• It is blinking red when the sleep mode has been enabled
and the receiver is currently running a session. With the
sleep mode enabled, the receiver is idle between any two
sessions, as if it were virtually turned off, and the power
LED is also turned off during this time.

Log Button. Press this button briefly to start recording raw
data on the selected storage medium.
Another short press on this button will immediately stop raw
data recording.
Scroll button. Press this button briefly to scroll through the
different pages of information viewed on the screen.
If an alarm is reported on the display screen, a short press on
the Scroll button will acknowledge the alarm. The Scroll
button will recover its display scrolling function only after all
the alarms have been acknowledged this way.
Another function of the Scroll button is to re-activate the
screen backlight after the latter has automatically been
turned off. The Scroll button is also used in the firmware
update procedure.
Rear View
DC Power Input. A Fischer, three-contact, female connector
[1] allowing the ProFlex 800 to be powered from either the
provided AC adapter (connect the cable extension between
ProFlex 800 and the end of the AC adapter output cable), or
an external 9- to 36-V DC power source through cable P/N
730477 (cf. base setup using an external radio transmitter).
GNSS Input #1 . A TNC coaxial female connector [2] allowing
you to connect a GNSS antenna to the receiver via a coaxial
cable.
[9] [3] [4] [5] [7] [1]
[6] [8] [2] [10]

8
Serial Data Ports. These are all Fischer, seven-contact, female
connectors, each allowing a serial connection to an external
device.
• Ports F [3] and B [4] are both RS232-only ports
• RS232/422 Port A [5] is a switchable RS232/RS422 port
(Default is RS232).
As an option (installed at the factory), port A also delivers
a regulated DC power voltage between pin 1 (+12 V DC)
and pin 2 (GND) that can be used to power a connected
device. The DC current available is 0.5 A steady state, and
1.0 A peak.
UHF Input. A TNC coaxial female connector [6] allowing you to
connect a radio whip antenna. This connector is available
only if the ProFlex 800 has been fitted with a radio module.
(Connector [6] is missing from the rear view above.)
Warning! Do not confuse this coaxial input with the GNSS
input [2] below. Connecting a GNSS antenna to the UHF
input might damage it if the embedded UHF transmitter is
used (although the transmitter is not supposed to transmit
until there are enough GNSS satellites received).
Ethernet Port. A Fischer, seven-contact female connector [7]
allowing you to connect the ProFlex 800 to a local network
(LAN). Through this connector, you may remotely control and
monitor the ProFlex 800 from any computer connected to the
Internet. Data may also flow through this port, in the same
way as through a serial port.
GNSS Input #2. A TNC coaxial female connector [8] for
applying an external reference clock. (Connector [8] is
missing on the rear view above.)

9
CAN 2.0 Bus. A Fischer, five-contact, female connector [9]
allowing you to connect the ProFlex 800 to external,
NMEA2000-compatible equipment via CAN bus. (For future
use.)
Earth Terminal. A screw terminal [10] for connecting the
receiver chassis to Earth.
Electric Isolation. All signals available on the following
connectors are optically isolated from the receiver’s internal
circuitry and chassis ground, as well as from each other:
• Serial ports A, B and F (including DC power output voltage
on port A)
• Ethernet port
•CANbus
Buzzer
The internal buzzer will sound whenever an error is detected.
The buzzer will sound six times and then stop. The error icon
will however continue to blink. To acknowledge the error
notification, first press the Scroll key to view the error and
associated code and then press the same button again.
Battery Model & Battery Compartment
The battery used is a 7.4-V DC - 4600 mAh rechargeable
battery. It is a standard model used in many camcorders.

10
The battery is housed in a battery compartment accessible
from above the ProFlex 800. The compartment door can be
opened by lifting and then turning the quarter-turn finger
screw counter-clockwise.
The battery will automatically operate as a backup power
source for the receiver if for some reason the external DC
source used is removed from the DC power input.
A slide switch is available at the bottom of the battery
compartment to set the behavior of the receiver after removal
or failure of the DC power source while the receiver is on:
• Slide switch pushed to the right: Automatic re-start. The
receiver will automatically be switched on when DC power
is restored. This is the typically the setting that should be
used with ProFlex 800 CORS.
• Slide switch pushed to the left: Manual re-start. After
power is restored, the receiver will stay off. Operator
intervention is needed to switch the receiver back on.
Use for example the tip of a pen to slide the switch to the left
or right.
Special Button Combinations
• With the ProFlex 800 OFF, pressing the Power, Log and
Scroll buttons simultaneously for a few seconds will
restore all the factory settings.
• With the ProFlex 800 OFF and a USB key connected,
pressing the Power and Scroll buttons simultaneously for
a few seconds will cause the ProFlex 800 to start a
firmware upload process. If there is no USB key
connected or the key does not contain a firmware upgrade,
then the process will abort after a few seconds.
Because data has to be decompressed on the USB key
during upgrades, the USB key must be unlocked, with at
least 100 MBytes of free memory, before starting the
upgrade.
These button combinations are summarized in the table
below:

for several hours after a power shutdown, giving you the time
to take the necessary maintenance steps.
Follow the instructions below to charge a battery.
Removing the Battery from the ProFlex 800
Unless the battery has already been taken out, do the
following:
• Open the battery trapdoor, accessible from above the
ProFlex 800, by lifting and then turning the quarter-turn
finger screw anticlockwise. This releases the two springs
located under the battery, pushing the battery slightly
upward (see picture).
• Grab the battery and take it out of the compartment.
Charging the Battery
The battery charger comes with a separate universal AC
adapter fitted with a 1.5-m output cable. The AC adapter
includes a choice of four different, detachable plug types.
Follow the instructions below to operate the charger.
• Choose the plug type that is suitable for your country.
• Secure that plug on the AC adapter.
• Connect the cable from the AC adapter to the battery
charger.
• Give the battery the right orientation with respect to the
charger [1] (the battery terminals should come into
contact with the two sets of connectors on the charger),
then push the battery against the plate and slide it forward
[2] until it locks into place.

• Plug the adapter into an AC outlet. Battery charging starts
immediately.
For a low battery that’s being charged, you will first see the
three LEDs switch on and off, one after the other, followed
by a short period of time when none of the LEDs is on (see
[3]).
After about two hours of charging, the MED LED will stay
on [4]. A few minutes later, the HI LED [5], and then the
MAX LED [6] will also stay on.
• When the three LEDs are on, this means the battery is
fully charged and can be disconnected from the charger.
Inserting the Battery in the ProFlex 800
• Insert the battery into the compartment making sure the
battery has the right orientation (the battery terminals
should come into contact with the two sets of connectors
located at the bottom of the compartment).
• Close the trapdoor, push the finger screw in tight, and turn
it fully clockwise.
Note that once it is properly secured, the trapdoor pushes
the battery against the bottom of the compartment to
ensure electrical connection of the battery to the ProFlex
800.

Power-On Screen
When you power on the receiver, the Ashtech logo appears on
the screen. It is displayed until the receiver has completed its
auto-test (this takes about 30 seconds).
Then the General Status screen is displayed.
General Status Screen
An example of General Status screen is shown below.
This screen displays the following information:
• : Satellite icon [1] (always displayed).
• Number of satellites tracked [2].
• BASE [3]: A label indicating that the receiver is used as a
base.
• Number of satellites used [4]: Number of satellites
processed by the reference station and for which
corrections are made available to users. These satellites
are also used to compute an SDGPS solution of the base
position. This solution is permanently available on the
position computation screen (see Position Computation
Screen on page 16).
