Origin 600 draws 0.625 mA when sleeping, 25 mA when pinging, and 0.146 A when fully active.
The above currents have been calculated using P / V = I, where P = power, V = voltage and I = current.
The Origin 600 ADCP requires 18-48 V external power, so 24 V was taken as a standard voltage. Its power consumption is 15 mW while sleeping, 600 mW while pinging, and 3.5 W when fully active.
Origin produces acoustic data in three different file formats: PD0, A-gram, and B-gram. Each format is a binary file format that is not human-readable.
What is PD0?
We have a separate FAQ giving more detail on PD0 (which can be found here), but essentially, this is a binary, industry-standard data format that describes the velocity profile measured by the ADCP as a function of depth, along with other parameters such as backscatter intensity, derived metrics, and metadata.
What is A-gram?
A-grams are a binary format proprietary to Sonardyne ADCPs. Each A-gram contains water velocity data sampled along the slant range of a single beam, along with other parameters (such as backscatter intensity), derived metrics, and metadata. One A-gram contains information pertaining to one beam. Thus, for a single ping, Origin 600 will produce five A-grams, one for each beam.
What is B-gram?
B-grams are a binary format proprietary to Sonardyne ADCPs. Each B-gram contains raw acoustic data sampled along the slant range of a single beam, along with metadata. One B-gram contains information pertaining to one beam. Thus, for a single ping, Origin 600 will produce five B-grams, one for each beam.
How do A-gram and B-gram differ from PD0?
Like PD0, A- and B-gram hold common metadata. Formats differ by the extent to which data has been processed. It is possible to transform between the different data formats, but only in the order described below. It is not possible to convert from PD0 data to A-gram or B-gram, nor is it possible to convert from an A-gram to a B-gram.
When Origin pings and captures data, in the first processing step B-gram data is stored in memory. Each B-gram contains raw samples of the backscattered sound waves received by one beam. In the second processing step, the data content of a B-gram is processed to form the data content of an A-gram corresponding to that same beam. In the final processing step, once A-grams have been computed for all beams for that ping, they are binned into depth cells to produce one PD ‘ensemble’.
It is possible to connect acoustically with Origin both on dry land and with the ADCP in water. If you’re having trouble doing this, read on for some tips that should help you establish acoustic communication.
First steps
It’s important to determine the address of the Origin in-built acoustic modem before attempting any acoustic communications. The modem address can be found and (if necessary changed) from Origin Portal. You can also find the address when the ADCP is deployed if necessary. This can be done using an iWand or through the 6G terminal.
The desktop PC software Origin Topside provides an interface to communicate acoustically with Origin. Before attempting acoustic communications, the latest version of the Origin Topside software should be installed on the PC.
If you can’t connect to an ADCP in the water
We have a number of topside transponders to suit different conditions. The first thing to check is that you’re using a compatible topside acoustic modem, for example an Origin Nano Dunker or an HPT 3000, and that this has sufficient power.
The in-built Origin 600 modem has a typical slant range of around 500 m which should be accounted for when positioning a vessel or buoy for communications with Origin. While the ADCP modem has an omnidirectional beam, its angled position on the Origin 600 endcap means there is an optimal direction in which to approach the ADCP for acoustic communications (i.e., in the direction of the modem transducer face). If you can’t connect to the ADCP, try approaching from a different direction, or getting closer to the deployed ADCP. You should also make sure that there is nothing obscuring the line of sight to the ADCP.
In Origin Topside there is an entry field where you can type the approximate depth and range to the deployed ADCP. It is important to get this range as close as possible to reality, so if you can’t connect to your ADCP, try adjusting the numbers in this field. The range needs to be large enough to encompass the distance to the ADCP, but not so large that it adds gain to the topside transceiver and causes saturation. If you enter a range that is much too small, the command won’t be heard by the ADCP modem.
Make sure you’ve typed in the correct modem address in Origin Topside for the remote ADCP.
For more information on any of these issues and to see how to solve these issues in practice, see the FAQ section in the back of the Origin Topside manual.
If you can’t connect to the ADCP on land
There are a number of things you can check if you can’t connect to the Origin 600 ADCP on land.

Data stored on Origin 600 can be easily accessed in two ways: acoustically, or via an Ethernet cable directly to your laptop.
Accessing data via a cable
To access data stored on an Origin 600 via an Ethernet cable, follow the steps below. If you would prefer to see these steps in a follow-along video format, please visit this video on Sonardyne’s YouTube channel.
Accessing data acoustically
Due to the limited bandwidth of acoustics, it is not possible to acoustically download log files of native formats of Origin data (PD0, A-gram, and B-gram), or files of external sensor data. However, it is possible to acoustically download individual records of PD0 data via Origin Topside or Edge processed data.
To download data acoustically:
You can also view the latest PD0 ensemble via a dialogue box that shows beam-frame PD0 velocities, intensities, and cross-correlation scores (x-axis) against depth (y-axis).

When preparing beacons for deployment, it is important to ensure that they have sufficient remaining battery capacity for the intended deployment, and to consider the most appropriate beacon addresses.
The first important decision is whether the WB2, or WB2+ signal set is most appropriate. Note that the ‘+’ on the end of WB2 does not mean ‘better’, it indicates longer signals, which carries with it higher battery consumption, and potentially more reverberation noise in the water. WB2 signals should be the default choice unless there is a specific reason to choose WB2+.
It is usually more effective to tune power and gain than using longer signals; however longer signals are useful at the margins of detectability.
Sonardyne can provide support in predicting battery life given an expected signal set, power level, interrogation, and telemetry rate.

Our Deployment Machine, when correctly braced, is capable of handling prolonged speeds of 7 knots.
However, if the pole is accidentally left deployed, and the vessel sails to its next destination at a speed greater than this, then potentially‑catastrophic damage could result.
At best the pole could deform and bend, resulting in a replacement Deployment Machine and Transceiver.
At worst, the through-hull tube on which the Gate Valve sits could fail, possibly resulting in (at best) localised flooding.
Our most-recent Deployment Machine system, together with our latest Marksman and Ranger2 software, allows not only the machine to be operated from software (as well as from the normal push‑buttons on each control console), but also to warn the operator if the Deployment Pole is not fully recovered when the vessel exceeds 7 knots.
The following alarm message is displayed: “Deployment 1 is in the down position and vessel speed has exceeded the safety threshold of 7 knots”.
(“Deployment 1” is the default (changeable) name of the Deployment Machine.)
As well as alerting the operator both visually and audibly from Marksman/Ranger2 software, a telegram can also be configured to alert 3rd party equipment, such as the DP system – either via a serial (RS232/RS485) or UDP link.
Please contact us at [email protected] to discuss how we can provide this valuable safety feature.

What is a SPRINT-Nav & hybrid navigation?
SPRINT-Nav combines INS (inertial navigation system), DVL (doppler velocity logger) and a pressure sensor into a compact, single housing, providing an all-in-one navigation instrument for underwater and surface vehicles. At Sonardyne, we combine our SPRINT INS and Syrinx DVL alongside a high accuracy pressure sensor, to create the SPRINT-Nav system.
How does a SPRINT-Nav work?
The IMU (inertial motion unit) measures the vehicle’s orientation and acceleration whilst the DVL measures the vehicle’s velocity relative to the seabed or water column and the pressure sensor measures the vehicle’s depth.
To provide accurate and reliable navigation information, SPRINT-Nav uses a tightly coupled algorithm to fuse the data from these three sensors. The algorithm considers the errors associated with each sensor to produce a navigation solution that is more accurate than any one of the individual sensors could provide on their own. Special calibration is not required to be performed before or during the mission to SPRINT-Nav being pre-calibrated. This is because the SPRINT-Nav simultaneously runs two algorithms: an attitude and heading reference system (AHRS) algorithm and an inertial navigation system (INS) algorithm. The INS algorithm can instantly initialise from the AHRS algorithm, allowing SPRINT-Nav to be used immediately after being turned on.
It is also fast to initialise, even if the vehicle is in motion; this is due to the use of ring laser gyros in the IMU which are very accurate and stable gyros and are not affected by dithering- a small, high frequency vibration that can introduce errors in gyros.
How can SPRINT-Nav be used?
SPRINT-Nav has a wide variety of applications, here are some examples. For an ROV, SPRINT-Nav can be used for piloting and navigation as well as dynamic positioning and mid-water station keeping with sparse LBL. For all subsea survey operations, SPIRNT-Nav 300, 500 and 700 offer a range of capabilities to suit your needs. In addition to this, SPRINT-Nav Mini is ideal for deploying on inspection class ROVs and small AUV platforms. SPRINT-Nav U (the world’s smallest hybrid navigator) is ideal for the missions where you don’t want to deploy a large vessel. For AUVs, SPRINT-Nav X achieves high navigational accuracy, which allows for long-endurance missions. For USVs, SPRINT-Nav can be deployed for control tasks in GNSS (global navigation satellite system) denied environments as well as aiding station keeping. SPRINT-Nav Mini can also be used as a dynamic positioning reference unit. Looking for SPRINT-Nav DP? Read our dedicated article to understand what SPRINT-Nav DP is and how you can use it.
