3 About Lodestar

3.1 Introduction

Sonardyne International Limited has applied its comprehensive experience in

producing advanced and dependable marine solutions to the development of the

Lodestar Attitude and Heading Reference System (AHRS) / Inertial Navigation

System (INS).

The Lodestar is a solid-state AHRS/INS that includes three Ring Laser Gyroscopes

(RLGs) and three linear accelerometers. These inertial-grade components provide

raw data to the Sonardyne-developed gyrocompass algorithm, which uses them to

produce a full range of accurate real-time motion and attitude measurements in all

sea states.

Developed originally to provide accurate heading and attitude measurements for

Sonardyne’s family of acoustic positioning systems, Lodestar is equally suited to a

variety of o

ther applications where the accuracy of heading and attitude

measurements is of critical importance. Lodestar can operate either as a stand-

alone AHRS or as part of an integrated system.

Lodestar is available in surface and subsea versions, where Sonardyne’s

experience with underwater acoustic navigation systems has been applied to

overcome the problems associated with conventional sensor platforms, such as

temperature shock.

Lodestar provides the following as standard:

•industry-standard output telegrams

•battery backup to maintain uninterrupted operation in the event of brief power

failure

•Battery operation will last up to two hours when using a battery from a fully-

charged condition.

•8 GB of internal memory.

•Upgrade capability to a full Inertial Navigation System

(INS) that provides

additional outputs of position, velocity, orientation and angular velocity at high

update rates.

•0.03° secant-latitude heading accuracy.

•0.01° roll and pitch measurement accuracy.

•Fast follow-up speed of 500° per second.

•Single-box solution for motion sensor and gyrocompass.

•No dedicated GPS receiver necessary.

•A settling time of less than five minutes.

•Support for all industry-standard telegrams.

•Ethernet interface as standard.

•Mean Time Before Failure (MTBF) for the IMU in excess of 100,000 hours.

•Low life-cycle cost.

•Flexible mounting arrangements.

•Low current draw on start-up.

•Choice of three subsea unit depth ratings – 1000, 3000 or 5000 metres.

•Heave measurement accuracy the greater of 5 cm or 5% of measured heave.

•Robust heave algorithm.

•Data output through RS232 or RS485 serial or Ethernet interfaces.

Issue: A– Rev

The Lodestar has undergone independent and exhaustive testing against an

industry-recognised reference

and has proved capable of delivering accurate

measurements in highly dynamic marine environments. Lodestar benefits from

Sonardyne’s world-class manufacturing, support and training organization, which

has a well-established record for providing trusted solutions.

3.2 Front panel features of the Surface Lodestar

Sonardyne has designed the Lodestar AHRS to be as simple as possible to install,

connect, configure, and operate. To support this design principle, the front panel of

the Surface Lodestar has only a single operator control, a series of LED status

indicators, and eight

ports to connect Lodestar with external equipment and

supplies. The Surface Lodestar is shown in Figure 1.

Figure 1 – Surface Lodestar – Front Panel

Table 1 lists and describes the connection ports on the front panel of the Surface

Lodestar.

Console Port

A 14-way female Lemo port that allows

connection of a PC to communicate with

the

Lodestar for configuration or data

logging purposes. DC power for the unit

may be connected here (24 / 8 V

nominal).

IMPORTANT: The console port

connection uses a channel select line

to specify RS232 (default) or RS485.

–

Connect Channel select to ground if

you are using RS232.

– Leave Channel select disconnected if

you are using RS485

RS485/

RS232_2a

Two 12-way female Lemo ports that allow

serial data connection between the

Lodestar and external equipment. These

ports are both available to:

•transmit measurements from the

Lodestar to receiving equipment

•

receive aiding information from

external sources, for example a

GPS receiver

•send or receive a trigger signal

8084-134

Transceiver

Ports

A 10-way female Lemo port that allows

direct serial connection between Lodestar

and Sonardyne acoustic transceivers or

other external instruments.

These ports are also both available to:

•

transmit measurements from

Lodestar to receiving equipment

•

receive aiding information from

external sources, for example a

GPS receiver.

•send or receive a trigger signal

Power In

A 3-way male inlet port that accepts

electrical power from an external mains

electrical source. This port accepts 110 /

230 V AC at 50 / 60 Hz.

Lodestar draws a maximum 20watts from

the external power. There is a 500mA(T)

fuse in line with

the external electrical

supply. The fuse is accessible without

disassembling the unit.

8084-054

Ethernet

A 100BaseT Ethernet port.

aWhen using Lodestar to supply NMEA outputs to multiple listening devices, use a two-wire shielded

twisted pair. See section 5.7 beginning on page 31 for information. The RS485 differential line consists

of two pins – ‘A’ and ‘B’ as defined in the NMEA standard:

‘A’ (TxD– / RxD-), or the inverting pin, is negative (compared to B) when the line is idle (data is 1)

‘B’ (TxD+ / RxD+), or the non-inverting pin, is positive (compared to A) when the line is idle (data is 1)
