The **Launch and recovery system**, also known as LARS, is a machine designed to load the rocket launcher, carry out a test fire, and return to its original position. It is mainly used for marine and subsea purposes. 
LARS is a hydraulic A-frame coupled with a compact and robust diving cage.

## Purpose Of Lars

The **[launch and recovery system](https://www.okeanus.com/products/launch-and-recovery-systems)** is a component of a space capsule that provides the means to send, receive, and reuse it. The systems are developed depending upon the environmental conditions and requirements. The marine equipment engineers customize the LARS system depending on the purpose of the operation.
Some people undergo marine science programs for investigation and research that require marine scientific research equipment as per their needs.
There is various equipment used while building the LARS system. 
The Boat LARS serves the purpose of fast deployment and recovery of an RHIB. Launching and recovering RHIBs from a mother ship enables the deployment of personnel and equipment at sea. This system allows the sea vessel to carry out different naval warfare operations.

## Benefits Of Renting Lars Systems From A Renowned Provider Include:

- Available with various kinds of class approval
- Custom-made system for each application
- Works efficiently in harsh marine environments
- Completely reliable and durable system

## Some Functional Marine Equipment And Systems And Their Uses

### • Umbilical Winch And Its Characteristics

The most important element used in the LARS systems is the **[umbilical winch](https://www.okeanus.com/products/specialty-winches)**, primarily used to pull the cable from the boat on a wire rope. This device can be used for both loading and unloading cargo. The umbilical winch further raises or lowers the cable depending on the task.
Moreover, it can also be used to carry out a test-fire of the launcher and retrieve information from the devices. The retrieved data can be viewed on a real-time basis. 
The winch can be attached to your boat using a custom tag.

Some characteristics of umbilical winch are listed below: -

- Stainless steel pipes and fittings
- Hydrostatic drive
- Lifting frame
- Separate electro-hydraulic power unit
- Fail-safe hydraulic brake
- Proportional remote-control valve
- Electroactive wind at right angle level

### • Ultra Short Baseline System And Its Work Methodology 

For carrying out deep-water explorations and operations, it's essential to know the object's position information. With the help of the Ultra Short Baseline system, you can locate any underwater object's position. Based on the baseline length of the acoustic positioning system, the positioning systems can be classified traditionally as three different types such as: -
        1. Short baseline positioning system
        2. Long baseline positioning system
        3. Ultra short baseline positioning system

The efficiency, accuracy, cost-effectiveness, and simplicity of the USBL make it relatively an advantageous one. The USBL application system is widely used for monitoring and finding the position of underwater objects such as: -

- Pipeline crossing mattress position
- Pipeline lay down head position
- Diver and ROV positioning and guidance
- Pipeline touchdown monitoring
- Pipelines spool piece position

The following are the two main components of the Ultra short baseline: -
       1. Transceiver
       2. Beacon or a transponder
A transceiver is used to transmit and receive the signal. At the same time, a beacon or a transponder replies to inquiries from the transceiver. The navigation control unit regulates all these processes.
An acoustic pulse is transmitted by the transceiver and received by the transponder. It then transmits back its acoustic pulse. The **[Ultra short baseline](https://voticle.com/a/articles/242603/ultra-short-baseline-the-ultimate-submarine-positioning-system)** system records the time frame between the transmission and receipt of both the vibrations. Further, this time frame is then converted into a range.
