Customer support services include: technical support, training, hardware maintenance and software maintenance.

Engineering services are: installation, putting into operation, planning, engineering, upgrading и uninstallation.

Product lifecycle spans from the start of product sales until the last product of that type is in service. Each installation of a product lives its own service life which lasts from installation to deinstallation. Product lifecycle refers to product type, meaning all installations of a certain product.

Service life starts at takeover. During the service life, customer enjoys support services, depending on the current product lifecycle phase.

Declaration of "End of Support" doesn't mean that product and customers still using the product are forgotten. After support has ended, GVS makes available resources enabling customer himself or third parties to continue supporting the product. This phase is thus referred to as "Self-support".

There are four phases in product lifecycle:

• mainstream support phase - product is actively developed
• extended support phase - from "End of Development" until declared "End of Life"
• maintenance phase - repair service and spare parts are available, software is actively maintained
• support phase - GVS service center does not provide repair services, but offers technical support to customers or third parties providing those services

Warranty period starts usually starts at product acceptance and it may be different for each product installation. Relating to product lifecycle, warranty period is negotiable.

Product Development

We offer R&D services for electronic products and systems completely lead by technical specifications from the customer.

• Electronic hardware development both analog and digital, microprocessor controlled systems, power converters and RF units.
• IP design for FPGA, both purely digital and mixed analog-digital programmable components
• We develop firmware with optional formal verification, with a vast field-proven library of in-house developed re-usable modules

Software Development

For purely software products, we provide software development services:

• We specialize in design and implementation of real-time, high reliability and high availability software.
• In software development, we champion an approach which introduces quality in the design and implementation, with strong and “omni-present” QA to prove the quality rate.
• We have vast experience in HW/SW co-design and co-verification, which enables development of highly integrated and robust products and systems.
