Project Services
We at SGS Weather provide services including installation, operation, maintenance, equipment calibration and more.
We have the biggest fleet of service engineers in the field in India. Our service programs are tailor made as per the customer needs. The flexibility in our
approach is the key to our success. We endeavor to provide the technology at it best with simplified operations. With our value added services and turnkey
solutions, we have changed the project concept in the field of Environment and Meteorology in India.
We broadly classify our services as
Turn- key Implementation of Projects
A turnkey is a type of project that is delivered as a completed product. As being a manufacturer and system integrator,
we add features and services to an existing cutting edge technology products, then execute as an integrated product or complete "turn-key" solution.
This practice occurs commonly with the customers where their requirement is beyond the standard industry products and is bundle with a software
application, product outputs, special service requirements and operational manpower needs also with supplied hardware.
The ‘added value’ comes from our professional services such as integrating, customizing, training and implementation etc along with
manufacturing and fabrication of specialized components and fixtures. The value is also added by developing a specific application for the product
designed for the customer's needs which is then resold as a new package. We accomplish this by having an in-house blend of experience, knowledge and
ability, which allows us to select and provide the best available solution that match our customers’ requirements.
We provide overall project execution services using qualified, skilled and experienced field engineers to execute onsite projects.
The primary aim of our company is the provision of an ‘Integrated Approach’
to project execution for all types of Weather & Environmental needs of our customers and provide long term support service for trouble free operation of systems.
Exhaustive and Interactive Training Programs
Training is the acquisition of knowledge, skills and competencies as a result of the teaching of vocational or practical skills and
knowledge that relate to specific useful competencies. Training has specific goals of improving one's capability, capacity, productivity and performance.
We at SGS Weather understand that training forms the core of any project and provides the backbone for the quality operations and upkeep of the systems. In
addition to the basic training required to understand the system, we provide training beyond initial qualifications: to maintain, upgrade and update
skills throughout the project lifecycle.
With exponential development of complexity of the technology, the customer requirements are more demanding and dynamic in nature. We understand this change a
nd our training programs are designed from the simple operations and operational level maintenance to complex spare part replacement at sites.
Our customer training programs can be characterize into a number of discrete components, each addressing a different part of the overall learning process as below
For complex multi-user system, SGS often constructs a user-to-task map to present the relationship between the tasks and the identified
team structure and
also to identify new groups of users that would need to have an understanding of the system. The training gap is assessed by a comparison between the goals
and tasks undertaken by the individuals and the existing training. There is a wide variety of training media that we use, ranging from traditional lecture-based
teaching to sophisticated simulators. We also make movies for project installation & maintenance and the results to visual training has been the most successful.
Our core business strength is providing a broad range of our training services to all customers and having a satisfied base of
references in Weather & Environmental in closely knitted scientific community.
Data Backup, Archival
The end product of our systems and the projects is “DATA”. Normally it is voluminous and a proper planning and expertise is required to handle
and upkeep the data. We at SGS Weather provide the complete solutions and support for Data Backup, Archival and dissemination.
Data archiving is the process of identifying and moving inactive data out of current database systems and into specialized long-term archival storage systems. Moving
inactive data out of online systems & Servers optimizes the performance of resources needed there while specialized archival systems store information more cost-
effectively and provide for retrieval when needed. Data archiving is the process of moving data that is no longer actively used to a separate data storage device for
long-term retention. Data archives consist of older data that is still important and necessary for future reference, as well as data that must be retained for regulatory
compliance. Data archives are indexed and have search capabilities so that files and parts of files can be easily located and retrieved.
Data archives are often confused with data backups, which are copies of data. Data backups are used to restore data in case it is corrupted or destroyed. In contrast,
data archives protect older information that is not needed for everyday operations but may occasionally need to be accessed. We at SGS Weather help the customer by
understanding its needs. We suggest and implement the most efficient way to handle the data by writing the scripts for the customer as per his existing and new infrastructure.
We set the policies for qualifying data to be moved into archives. These policy settings are used to automate the process of identifying and moving the appropriate data into
the archive system. Once in the archive system, information remains online and accessible. Original content is preserved to ensure complete, reliable integrity for the life
of the archived information. We also provide solutions for Cloud servers for data backup and archiving.
We provide lot of benefits to the customer by automating the data archiving and backup process and using purpose-built archive systems make On-line systems run better,
use less resources, and reduce overall storage costs. Online servers performance is unaffected by information growth. Backup and recovery runs faster, disaster recovery
is less costly, and systems are easier to manage. Data moved into archives is stored at much lower cost.
We also provide the Data dissemination on the internet cloud severs through many different kinds of communications protocols. The standard internet protocols are well
suited for local area networks (LAN) and wide area network (WAN) communication. We provide solutions for data Masking of structured data to ensure that data security is
maintained and sensitive information is not exposed to unauthorized personnel.
We ensure our customers for data security and integrity with fast & stable solutions for Data Backup, Archival and dissemination.
Detailed Project Preparation
SGS has dedicated team of experts for developing specialized systems on demand from user. Challenging projects are our first choice.
SGS Weather is a reliable name in the meteorological field for offering integrated technical support services. Our project support includes : Pre-feasibility study,
Technology Identification, Project Feasibility and Market Study, Identification of data utilization Opportunities, Preparation of Project Profiles and Preparation of
Techno-Economic Feasibility Reports.
Project Preparation consists of all the work necessary to ensure that a proposed project is technically feasible and appropriate and that it can be successfully implemented
as per customer requirements. The process ensures the identification and elimination of key risks at the earliest possible time and maximizes development opportunities by
ensuring that projects are well conceptualized.
Preparation work is social, technical and financial in nature. Typical preparation activities include: the identification of funding sources, needs assessments, community
and stakeholder, socio-economic studies, the development of project concepts, assessments of site suitability (e.g. topography and environmental conditions),
site availability, government rules and regulations, estimates for operational costs. Most of this work takes place during the pre-feasibility and feasibility phases.
Systematic and effective Project Preparation is important for a range of reasons outlined below:
- Project risks are managed and controlled.
- Scarce implementation resources are optimally utilized.
- Projects are well conceptualized and planned.
- Development is appropriately tailored to local needs and is integrated in nature.
- Government and other funders can predict and therefore manage their cash flows by enhancing the predictability of project outcomes and timeframes for implementation.
Project Preparation needs to be properly managed and coordinated and should be regarded as a project management function. Often government departments or other funding
agencies do not have the in-house personnel to undertake all the activities required for project preparation and typically the assistance of outside specialists is required.
Our core strength in project support is our team of expert advisors who understand the complete process and manage it effectively for the customers.

Solar Radiation Sensor Calibration
SGS Weather Calibration Lab is "one-stop solutons provider" for solar radiaton Calibration. We offer
indoor Calibration services of all makes and models of Pyranometers and Outdoor Calibraton Facility for
Phyreliometers. SGS Weather Solar Radiaton Calibration is designed to calibrate the all Pyranometers
according to the “Direct beam calibraton (type IIc) of the ISO 9847” Solar Energy – Calibraton of field
Pyranometers by comparison to a reference Pyranometer. During the calibraton procedure, the output signals
of both the reference and the test Pyranometer are recorded simultaneously. From these recordings, the
sensitvity of the test Pyranometer is calculated.
The Calibration process is controlled via a
dedicated user interface on PC. Data storage,
including data backup, and quality assurance of
the measurement (lamp stability and
homogenity) are taken care of by the control
unit. The procedure involves an unshaded and a
shaded measurement. The transition is done
using an automated shutter. The System is fully
automatic and the only manual operation is the

Pyranometer Calibration Procedure
We follow the instructions included in ISO 9847:1992 for pyranometers calibration. ISO 9847:1992
Solar energy – Calibration of field pyranometers by comparison to a reference pyranometer. The sesitivity of
the pyranometer under test (the 'test sensor') is determined by calibrating this pyranometer against a
reference sensor.
This calibration method is described in ISO 9847 as a type IIc Calibration, an indoor direct beam
Calibration. A reference pyranometer with a known sesitivity St in V/(W/m²) and a test pyranometer are
placed side by side under an artificial light source. A shaded, an unshaded and another shaded reading are
taken from both pyranometers, before the sensors are interchanged and the readings are repeated. A buzzer
alerts the user when the sensors need to be interchanged, or when an error occurs.
The sensitivity Sr in V/(W/m²) of the
pyranometer under test is determined by
St = Se (Vt + Vt’/Vr + Vr’)
Where Vt = Vt, − Vt,
Vtʹ = Vtʹ,u − Vtʹ,s
Vr = Vr,u − Vr,s
Vrʹ = Vrʹ,u − Vrʹ,s
With V voltage readings on the test (t) and
reference (r) pyranometer, respectively shaded
(s), unshaded (u), in original position (no
apostrophe) or in interchanged positions (with
apostrophe).
The shaded readings before and ater an
unshaded reading are linearized to find the
values for Vt, Vtʹ,s, Vr,s and Vrʹ,s.
Voltage readings are taken on a Campbell Scientific CR1000 datalogger. Expanded uncertainty of the
transfer itself is be calculated to be 0.5%. To find the uncertainty of the sesitivity of the test sensor, we include
the uncertainty of the reference sensor itself and that of any corrections that are applied. Standard Calibration
includes a measurement of the sensor resistance, the insulation resistance and the 95 % response time of the
test sensor.
Various digital pyranometers are supported, with slight changes to the measurement protocol. The
Calibration lab supports two different Calibration modes: side-by-side comparison and a single pyranometer
mode. The Calibration includes various levels of quality control on input parameters and measurement results.
The results are displayed on the Calibration Certificate.
Time taken by us for Calibration
2 working days after receipt of Pyranometer at our Calibration Center.
